Product: L6X® aluminum cylinder specifications

Our L6X all-metal cylinders are manufactured from our exclusive L6X aluminium alloy, our proprietary formula of 6061 alloy. Luxfer metallurgists, among the most recognized experts in the industry, developed this corrosion-resistant blend specifically to provide excellent performance in the most demanding high-pressure applications. Compared to conventional versions of 6061 alloy, Luxfer’s L6X has been optimized to improve durability, fracture toughness and resistance to tearing and cracking, even under high-pressure loads over long periods.

Because of the unique performance characteristics of L6X alloy, Luxfer has consistently passed all extensive, rigorous testing performed by major global gas companies and met or exceeded requirements set by every major cylinder regulatory authority in the world. Widely used in home oxygen therapy, emergency medical services and medical institutional applications in more than 50 countries, the more than 50 million cylinders Luxfer has manufactured from L6X alloy have an outstanding record for safe, dependable performance.

Product: L6X® composite cylinder specifications

Each ultra-lightweight L6X carbon composite oxygen cylinder has an inner liner made from Luxfer’s proprietary L6X alloy that is strengthened with an aerospace-grade carbon-fiber wrapping that completely surrounds the liner.

These extremely durable cylinders initially gained favor with firefighters who use them in self- contained breathing apparatus (SCBA). These cylinders are now also used by paramedics and other emergency first-responders. Because of their much lighter weight, compact size, higher capacity and excellent portability, Luxfer full-wrap cylinders are becoming popular in emergency and pre-hospital care, as well as for oxygen therapy, in which reduced weight and increased filling capacity provide significant advantages to ambulatory patients.

Product: L7X® aluminum cylinder specifications

Our L7X all-aluminium cylinders are manufactured from Luxfer’s higher-strength L7X aluminium alloy.
L7X advantages include higher-pressure filling of up to 300 bar for small cylinders (200 bar for large cylinders) and significantly more gas capacity with no increase in cylinder size and very little weight gain.

Product: L7X® hoop-wrap cylinder specifications

Our L7X hoop-wrap cylinders are manufactured with inner aluminium liners made from Luxfer’s 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 devolving.
