TUXING 30Mpa 4500Psi Carbon Fiber HPA Tank 0.7L - Compact

In this review the TUXING 30Mpa 4500Psi Carbon Fiber HPA Tank is presented as a compact, high-pressure option for shooters and divers who need a reliable small-capacity cylinder. The bottom line: this 0.7L (42 cu in) composite tank is for users who prioritize a lightweight bottle with industry-grade strength and a long design life, and the biggest reason to buy is the combination of a 300 bar working pressure with an imported AL6061 aluminum liner and carbon fiber winding for a strong but light package.

Key Features

• 0.7 L capacity: The 0.7 liter (42 cu in) volume keeps overall weight low while still providing usable fills for PCP rifles or short dives.
• M18x1.5 neck thread: The standard straight thread bottle mouth (M18x1.5) simplifies fitting to many paintball and PCP attachments and regulators.
• High working pressure: Rated at 30Mpa (300 bar / 4500 psi) this tank stores more gas per volume than lower pressure alternatives for compact use.
• Robust safety margins: The tank is hydrostatically tested to 50Mpa and specifies a 102Mpa minimum burst pressure, reflecting conservative safety engineering.
• Certified and durable: CE/EN approval, a 3-year inspection cycle and a 15-year design service life mean predictable maintenance and long-term use.
• Composite construction: An AL6061 aluminum alloy liner with carbon fiber and glass fiber winding keeps weight down while maintaining strength for outdoor and tactical use.

Who It's For

The TUXING 0.7L tank is best for PCP air rifle owners, paintball players, and anglers or divers who need a compact emergency air or fill bottle that is easy to carry on a pack or a gun case. It is particularly suited to users who value a high working pressure in a small form factor and who have regulators that accept an M18x1.5 straight thread.

This is not the best choice for users who require long duration fills for extended dives or multi-day field use, where larger-volume cylinders or multiple bottles are more practical. Also, those who need DOT certification for specific transport or regulatory situations should look for DOT-marked alternatives.

Pros & Cons

Pros

• High 300 bar working pressure in a compact 0.7L volume makes it very portable for PCP and paintball use.
• Composite build with AL6061 liner reduces weight without sacrificing structural strength.
• CE/EN certification, 3-year inspection interval and 15-year design life provide clear maintenance expectations.
• Standard M18x1.5 neck thread fits common PCP and paintball fittings with the correct regulator.

Cons

• Small 0.7L capacity limits run time compared with larger tanks, so frequent refills are required for extended use.
• Not DOT certified, which can affect transport or compliance in some regions.
