L7X® hoop-wrap cylinder specifications

Our L7X hoop-wrap cylinders are manufactured with inner aluminium liners made from Luxfer’s patented L7X higher-strength alloy that provides not only superior mechanical characteristics, but also significant weight savings. L7X liners are strengthened along the parallel cylinder sidewall with ultra-high-strength fibre wrapping, resulting in a high performance cylinder that is compact, light in weight and extremely corrosion resistant. When charged to 300 bar these cylinders provide up to 50% more gas capacity than conventional cylinders that can only be charged to lower pressures—which means that fewer cylinders are needed to deliver the same amount of gas. L7X hoop-wrap cylinders are also up to 55% lighter in weight than steel cylinders and up to 35% lighter than all-aluminium cylinders. Because of the higher strength of L7X alloy, threads last longer and are less susceptible to damage from valving and devalving.
