If you’re diving into the depths of Abyss on Roblox, your tube isn’t just a piece of equipment—it’s your lifeline. I’ve spent countless hours exploring every corner of this underwater world, and I can tell you right now: your tube determines everything. How deep you can dive, how long you can stay underwater, how much fish you can haul back, and even how fast you can escape from aggressive sea creatures.
After testing every single tube in the game and analyzing the optimal upgrade paths, I’ve put together this complete guide to help you make smart decisions about which tubes to buy and which ones to skip entirely. Trust me, wasting money on the wrong tube can set your progression back hours.
| Feature | What It Does |
|---|---|
| Oxygen Capacity | Determines how long you can explore underwater before drowning |
| Max Depth | Sets the deepest point you can reach before taking damage |
| Weight Limit | Controls how many fish and items you can carry |
| Speed | Affects how fast you move through the water |
| Boost Ability | All tubes have a speed boost (hold Left Shift while swimming) |
Think of tubes as your diving vessel in Abyss. Every tube in the game comes with four core stats that directly impact your survival and efficiency. Unlike most Roblox games where equipment is just cosmetic, tubes in Abyss are absolutely essential for progression.
Here’s the harsh truth: if your oxygen runs out while you’re underwater, you die. You’ll lose 25% of your inventory AND 25% of your money. That’s not a small penalty—it can wipe out hours of grinding if you’re not careful.
The weight stat is equally critical. I’ve lost count of how many times I’ve had to leave behind rare fish because my tube couldn’t carry them. Every kilogram of weight capacity matters when you’re hauling valuable catches back to the Kraken to sell.
I’ve organized every tube in Abyss by progression tier. This isn’t just a random list—it’s based on hundreds of hours of gameplay and consultation with top players in the community.
| Tube Name | Price | Oxygen | Max Depth | Weight | Speed | My Take |
|---|---|---|---|---|---|---|
| Wooden Tube | Free | 40 O2 | 15m | 5kg | 20m/s | Your starter tube. Upgrade ASAP. |
| Old Tube | $50 | 55 O2 | 25m | 10kg | 20m/s | Skip this completely—waste of money. |
| Normal Tube | $425 | 70 O2 | 50m | 25kg | 20m/s | First real upgrade. Get this immediately. |
| Fire Tube | $1,500 | 90 O2 | 100m | 45kg | 20m/s | Skip this—save for Pufferfish Tube instead. |
| Pufferfish Tube | $2,850 | 110 O2 | 180m | 80kg | 22m/s | Essential mid-game tube. Worth every penny. |
The Wooden Tube is your freebie at the start. It’s trash, but it gets you through the tutorial. The Old Tube is a trap—the upgrade is so minimal that you’re better off saving that $50 for better equipment.
Your first meaningful purchase should be the Normal Tube for $425. This gives you enough oxygen and depth to complete the early Kraken quests without constantly returning to the surface. I was able to farm the Forgotten Deep efficiently with this tube for several hours.
The Fire Tube? Skip it. The stats improvement over the Normal Tube doesn’t justify the $1,500 price tag. You’re better off grinding a bit longer and going straight for the Pufferfish Tube.
The Pufferfish Tube is where things get serious. With 110 O2 and 180m max depth, you can finally reach the Ancient Sands biome (which starts around 120m deep). The 80kg weight limit also means you can carry significantly more fish per run. This tube carried me through mid-game until I had enough cash for the next big upgrade.
| Tube Name | Price | Oxygen | Max Depth | Weight | Speed | Location |
|---|---|---|---|---|---|---|
| Boat Tube | $5,250 | 130 O2 | 275m | 120kg | 22m/s | Marcus (Ancient Sands) |
| Zepeline Tube | $18,500 | 150 O2 | 375m | 155kg | 24m/s | Diver NPC (Complete 5 quests) |
| Rukiry Tube | $40,500 | 180 O2 | 460m | 200kg | 24m/s | Top of Grumpy Hunk’s Tower (Ancient Sands) |
The Boat Tube is your first purchase from Marcus in Ancient Sands. At $5,250, it’s pricey, but the 275m depth lets you access areas that Pufferfish Tube simply can’t reach. The 120kg weight is also a massive improvement for fish hauling.
Here’s where strategy comes in: some players skip the Boat Tube entirely and save for the Zepeline Tube. This requires completing 5 quests from the Diver NPC (found atop a sunken submarine in Forgotten Deep), but the $18,500 investment gives you 375m depth and 155kg weight. That’s enough to reach Crazy Jeff’s Store at 230m depth.
I personally went Pufferfish → Boat → Zepeline, but if you’re patient and don’t mind slower progression, going Pufferfish → Zepeline is more cost-effective.
The Rukiry Tube is the king of mid-game. At $40,500, it’s expensive, but 460m depth and 200kg weight open up the entire map for exploration. I grinded with this tube for days before I could afford my late-game upgrade. You can buy it from the top of Grumpy Hunk’s Tower in Ancient Sands—just climb to the peak and you’ll find the vendor.
| Tube Name | Price | Oxygen | Max Depth | Weight | Speed | Location |
|---|---|---|---|---|---|---|
| Oxy Tube | $84,500 | 220 O2 | 495m | 250kg | 28m/s | Spirit Roots |
| Plane Tube | $90,500 | 260 O2 | 550m | 305kg | 28m/s | Diver NPC (Complete 5 more quests) |
| Lost Spirit Tube | $150,000 | 300 O2 | 600m | 370kg | 30m/s | Spirit Roots |
| Bath Tube | $256,000 | 320 O2 | 650m | 600kg | 27m/s | Bob’s Room (Forgotten Deep) |
| Ruined Tube | $270,000 | 380 O2 | 650m | 480kg | 32m/s | Angler Cave (Forgotten Deep) |
Once you hit late game, you’re looking at tubes that cost six figures. These aren’t for casual players—you’ll need serious grinding and smart fish sales to afford them.
The Oxy Tube and Plane Tube are solid choices for late-game exploration. I went with the Plane Tube because the 260 O2 and 550m depth let me explore the deepest biomes without stress. The $90,500 price tag hurts, but it’s worth it if you’re serious about completing the bestiary.
The Lost Spirit Tube requires $150,000 but offers insane stats: 300 O2, 600m depth, and 370kg weight. This is the tube I used to farm the rarest fish in Spirit Roots. The 30m/s speed also makes it the fastest non-Ruined tube in the game.
For end-game, you have two choices: Bath Tube or Ruined Tube.
The Bath Tube has the highest weight capacity in the game at 600kg. If you’re focused on maximizing fish hauls and making money, this is your tube. However, it only has 320 O2 and 27m/s speed, making it slower than alternatives.
The Ruined Tube is the absolute best tube in Abyss. Period. It has 380 O2 (highest in game), 650m max depth, 480kg weight, and a blazing 32m/s speed. This tube lets you explore every single area of the map with zero restrictions. To get it, you need to complete the Lost Captain questline to unlock the Angler Cave in Forgotten Deep, then buy it from the Lightkeeper NPC for $270,000.

Getting tubes in Abyss is straightforward you buy them from NPCs scattered throughout the map. However, some tubes have special requirements.
David’s Tube Shop (Forgotten Deep): This is your main tube vendor for early game. Located inside the safe dome in Forgotten Deep, David sells:
Walk up to David, press E to interact, and browse his inventory. Once you purchase a tube, it goes into your backpack.
Marcus (Ancient Sands): Marcus is both a merchant and quest-giver. He sells the Boat Tube for $5,250. You’ll find him beside his shop sign in Ancient Sands.
Some of the best tubes require completing NPC questlines first.
Diver NPC (Forgotten Deep): The Diver sits atop a sunken submarine in Forgotten Deep. Complete his 5-quest chain to unlock the Zepeline Tube ($18,500). After you finish all 5 quests, he’ll also sell the Plane Tube ($90,500).
Grumpy Hunk’s Tower (Ancient Sands): Climb to the very top of this tower to find the Rukiry Tube vendor. No quests required—just $40,500.
Bob’s Room (Forgotten Deep): Bob won’t let you in his room until you collect and bring him all the rubber ducks scattered around the map. Once you do, he’ll grant access, and you can buy the Bath Tube for $256,000.
Lightkeeper NPC (Angler Cave): Complete the Lost Captain questline to unlock the Angler Cave entrance. Inside, the Lightkeeper sells the Ruined Tube for $270,000.
This is important—buying a tube doesn’t automatically equip it. I made this mistake early on and couldn’t figure out why my stats weren’t updating.
Here’s how to equip a new tube:
Your new tube will replace your current one immediately, and your oxygen, depth, weight, and speed stats will update.
After testing multiple paths and analyzing the math, here’s the most efficient tube progression for 2026:
Total Investment: $428,525
This path hits every major milestone and never leaves you struggling. It’s slower, but you’ll always have the right tube for your current depth level.
Total Investment: $420,425 (saves $8,100)
This path skips Pufferfish and Boat tubes by grinding longer in early-mid game. The Normal Tube can get you to 50m depth, which is enough to farm decent fish and save for the Zepeline. Once you have Zepeline, you can reach Ancient Sands and farm harder to afford Rukiry.
Total Investment: $460,925
This path skips the most tubes but requires intense grinding with limited depth access. Only attempt this if you’re experienced with the game mechanics and know exactly which fish to target for maximum profit.
Not all tube stats are created equal. Here’s what you need to prioritize at each stage:
This is your survival timer. More oxygen = more time underwater = more fish caught per dive.
Early game: 70-110 O2 is fine. You’ll be making frequent trips to the surface anyway.
Mid game: 150-180 O2 lets you explore thoroughly without rushing.
Late game: 260+ O2 means you can camp in the deepest areas and fill your entire weight limit before returning.
Pro tip: Certain artifacts can boost your oxygen regeneration. Combine these with high O2 tubes for maximum efficiency.
This is the hard gate for progression. If a biome is at 200m and your tube maxes out at 180m, you can’t go there. Period.
The game uses depth zones:
Match your tube’s max depth to the zones you want to access. There’s no point buying a tube with 600m depth if you’re only farming at 200m.
Every fish has a weight value. Rare fish are heavier. Your tube’s weight limit determines how many fish you can carry before you’re overencumbered.
When you hit your weight limit:
I always aim for tubes with weight limits that are at least 2x my average catch value. This gives me buffer room for unexpected rare spawns.
Speed affects base movement and boost speed. Higher speed means:
The Ruined Tube’s 32m/s speed is game-changing. You zip around the map so fast that oxygen barely feels like a constraint.
Every tube in Abyss has a boost ability that most new players don’t even know exists.
How to use: Hold Left Shift while swimming.
Your tube will activate a speed burst, dramatically increasing movement speed. This is crucial for:
The catch: Boost drains oxygen WAY faster than normal swimming. I only use boost in emergencies or when I’m heading back to sell fish and my oxygen is topped off.
Pro strategy: Use boost to cover dead zones (areas with no fish) and conserve oxygen in high-value fishing spots.
Mistake 1: Buying Old Tube and Fire Tube
These tubes are noob traps. The stat improvements are so marginal that you’re better off grinding a bit longer and skipping straight to better options. I wasted $1,550 on these tubes before I realized my error.
Mistake 2: Not Equipping New Tubes
I bought the Normal Tube and spent 20 minutes wondering why I was still drowning at 20m depth. Turns out I forgot to equip it from my backpack. Don’t be me.
Mistake 3: Prioritizing Weight Over Depth
Weight is useless if you can’t reach the biomes where valuable fish spawn. Always prioritize max depth first, then oxygen, then weight, then speed.
Mistake 4: Selling Fish Before Upgrading Tubes
Fish values scale with depth. A rare fish from Spirit Roots sells for 10x more than a rare fish from Forgotten Deep. Rush your tube upgrades first, THEN focus on money grinding.
Mistake 5: Ignoring Tube Boost
The boost mechanic saves lives. I can’t count how many times I’ve boost-sprinted away from a shark with 2 seconds of oxygen left. Master the boost or pay the death penalty.
Abyss has multiple progression systems: Tubes, Guns (harpoons), Artifacts, and Races. Here’s how tubes fit into the bigger picture:
Tubes: Control WHERE you can go and HOW LONG you can stay.
Guns: Control HOW EFFECTIVELY you catch fish.
Artifacts: Provide passive bonuses (oxygen regen, fish detection, etc.)
Races: Give permanent stat buffs and special abilities.
My recommended priority order:
You can have the best gun in the game, but if your tube can’t reach the 500m zone, it’s worthless. Always upgrade tubes first.
For Money Grinders: Bath Tube ($256,000)
For Explorers: Ruined Tube ($270,000)
For Budget Players: Normal Tube → Zepeline Tube → Rukiry Tube
For Completionists: Ruined Tube (mandatory)
Late-game tubes cost $100,000+. Here’s how I farmed the cash:
Use your current tube’s max depth to find the deepest biome you can access. Camp there and specifically hunt rare fish (orange and red markers). One rare fish from Ancient Sands sells for $2,000-$5,000.
Many NPC quests reward $10,000-$25,000 on completion. Prioritize quest chains that give large cash rewards.
Geodes contain valuable loot. I found geodes worth $50,000+ in Spirit Roots. Learn geode spawn locations and farm them during cooldowns.
Some players use the Sell Anywhere gamepass and AFK fish in safe zones. I don’t recommend this as it goes against the intended gameplay, but it’s technically possible.
If trading is enabled in your server, buy undervalued rare fish from other players and resell at market price. This requires market knowledge and risk tolerance.
I personally used Method 1 combined with Method 2. Rare fish farming while completing quests gave me steady income and kept gameplay varied.
Based on Discord discussions and developer hints, here’s what might be coming:
Mythical Tubes: Tubes with special abilities beyond stat boosts (oxygen regeneration underwater, fish attraction radius, etc.)
Customizable Tubes: Mod system to swap out parts and customize your tube’s stats.
Tube Skins: Cosmetic variants that don’t affect stats but look cooler.
Rental System: Temporary access to high-tier tubes for limited-time events.
The Abyss developers are active on Discord and frequently tease upcoming content. Join the official server to stay updated.
You die and lose 25% of your current money AND 25% of your inventory. This penalty is brutal, especially late game when you’re carrying valuable fish. Always watch your oxygen meter and return to the surface with at least 10 seconds to spare.
No. All tubes are account-bound and cannot be sold, traded, or dropped. Once you buy a tube, it’s yours forever.
No. Tubes are permanent equipment with no durability system. Once purchased, they last forever.
Yes! You can own every tube in the game simultaneously. They all stay in your backpack’s Tubes tab. You can only have one equipped at a time, but you can swap freely without penalty.
Ruined Tube is objectively the best. 380 O2, 650m max depth, 480kg weight, and 32m/s speed. It costs $270,000 and requires completing the Lost Captain questline, but it’s the end-game tube for a reason.
Skip the Old Tube and Fire Tube. They’re not worth the investment. Focus on tubes that provide significant stat jumps: Normal → Pufferfish → Zepeline → Rukiry → Plane → Ruined.
Ask yourself: “What depth do I need to access next?” Match your tube purchase to the biome you’re trying to unlock. If Ancient Sands starts at 120m, buy a tube with at least 180m max depth.
No. Artifacts provide bonuses (like +10% oxygen regeneration or +5% movement speed), but they can’t overcome hard depth limits. You need the right tube to access deeper zones.
Farm rare fish in Spirit Roots with the Lost Spirit Tube or Plane Tube. Sell everything immediately and save every penny. Complete the Lost Captain questline in parallel. Expect 10-15 hours of grinding if you’re efficient.
The community has found several hidden tube locations:
Check the official Abyss Discord for the latest discoveries. The community uncovers new secrets weekly.
Your tube progression defines your Abyss experience. Every depth upgrade unlocks new biomes, new fish, new challenges, and new rewards. I’ve spent over 100 hours in this game, and I can confidently say that smart tube management is the #1 factor separating efficient players from those who struggle.
Don’t waste money on marginal upgrades. Focus on tubes that open new content. Prioritize max depth over everything else. And most importantly, always equip your new tube after buying it (I’m still salty about that mistake).
The ocean depths are waiting. Your tube is your only protection against the crushing pressure, the oxygen void, and the creatures lurking below. Choose wisely, upgrade strategically, and you’ll conquer every zone Abyss has to offer.
Now get out there and start diving. The Ruined Tube won’t farm itself, and those rare fish in Spirit Roots are worth a fortune.
