Serious airgun enthusiasts and divers, this TUXING carbon fiber HPA tank is professional-grade equipment at an amazing value! The 2-liter capacity gives you 122 cubic inches of air storage at a massive 4500 PSI (300 bar) working pressure. The carbon fiber construction wrapped around a 6061 aluminum alloy liner makes this tank incredibly strong yet surprisingly lightweight at just 1.6kg. The high-purity carbon fiber is wear-resistant and impact-resistant, while the specially treated inner surface ensures the air stays clean and pure for your equipment. The M18x1.5 straight thread bottle mouth connects directly to most air compressors and PCP air rifles. This tank is incredibly versatile - use it for charging PCP paintball markers, airguns, scuba diving, snorkeling, emergency escape systems, and even medical or firefighting applications. The full-wrapped carbon fiber and glass fiber winding creates a tank that's both lighter and stronger than all-steel alternatives. No more worrying about running out of air during extended shooting sessions or dives - this large capacity keeps you going longer. The workmanship is excellent throughout, with attention to detail that inspires confidence in the safety and reliability. Whether you're a competitive shooter, serious hunter, or diving enthusiast, this tank delivers the performance and capacity you need without breaking your back with heavy equipment.
