TUXING 4500Psi Carbon Fiber Scuba Tank 2L/122Cu in - Lightweight, High

In this review the TUXING 4500Psi Carbon Fiber Scuba Tank is evaluated for divers and airgun users who need a compact, high-pressure vessel. The bottom line: this 2L/122Cu in (2000CC) composite cylinder delivers a strong combination of lightweight design and high working pressure, making it a sensible choice for short dives, snorkeling trips, or PCP air rifle fills where portability and durability matter most.

Key Features

• Durable Construction: Carbon fiber composite construction provides exceptional strength and resistance to corrosion, which helps the tank withstand repeated outdoor use.
• High Working Pressure: Rated to 4500Psi (300 BAR working pressure), the cylinder stores a large volume of compressed air for its size, extending usable time underwater or between fills for PCP rifles.
• Compact Capacity: The 2L/122Cu in/2000CC actual volume offers a portable air supply that balances weight and usable air for short recreational dives and surface water activities.
• Lightweight Portability: At approximately 1.6 kg actual weight, the composite bottle is easy to carry and stow, reducing fatigue on hikes or boat trips compared with heavier metal tanks.
• Long Service Life: Designed working life of 15 years with a 3-year re-test period offers predictable long-term use and routine maintenance intervals.
• Versatile Use: Suited for scuba diving, snorkeling, PCP air rifles, and other water sports that require reliable high-pressure air delivery.

Who It's For

The TUXING 4500Psi tank is best for recreational divers, freedive support, snorkelers needing an emergency air source, and PCP shooters who want a portable, high-pressure fill option. Its lightweight carbon fiber build and compact 2L capacity make it especially useful for day trips, kayak or small-boat use, and owners who value easy transport over long bottom times.

Buyers who need extended full-scuba profiles, technical diving mixes, or larger-duration dives should look for larger cylinders; this tank is not intended to replace standard SCUBA tanks for long dives. Also, those unfamiliar with high-pressure handling should ensure local fill facilities and proper adapters are available before purchase.

Pros & Cons

Pros

• Very lightweight composite construction reduces carry weight and is corrosion resistant.
• High working pressure (300 BAR / 4500Psi) gives a compact tank a comparatively high usable air content.
• Durable design and a 15 year working life provide long-term value when properly maintained.

Cons

• 2L capacity limits underwater time compared with standard scuba cylinders, so it is best for short dives or auxiliary use.
• Straight thread mouth (M181.5) and high pressure require correct fittings and access to compatible fill stations.

Frequently Asked Questions

Is this tank safe for diving?
Yes, the tank is designed for underwater use with a 300 BAR working pressure and a 500 BAR hydraulic test pressure, but it must be maintained and re-tested every 3 years as specified.

What fittings does it use?
The bottle mouth uses a straight thread M181.5 fitting, so ensure you have compatible valves and fill adapters for your gear or local fill station.

How long will a fill last?
With a 2L/122Cu in volume, usable time is limited compared with standard scuba cylinders; it is best for short dives, surface support, or PCP fills rather than extended scuba profiles.
