Luxfer Gas Cylinders offers a broad range of high-pressure aluminum scuba cylinders, as well as the world’s only hoop-wrapped composite scuba cylinders.

More than 50 years ago, Luxfer developed the world’s first aluminum scuba cylinder in collaboration with the legendary Jacques-Yves Cousteau, inventor of the original Aqua Lung®1 equipment that revolutionized underwater diving.

The Luxfer Advantage

  • Proprietary L6X® alloy, a specially balanced aluminum-magnesium-silicon formula exclusive to Luxfer.
  • Luxfer scuba cylinders are manufactured to meet or exceed all recognized international standards.
  • Nitrox-ready—All new Luxfer scuba cylinders are prepared at the factory to be suitable for use with oxygen-enriched breathing mixtures.
  • Luxfer scuba cylinders are cycle-tested in excess of 100,000 cycles at service pressure.
  • Minimum burst pressure tested to 2.5 times service pressure without failure.
  • Corrosion-resistant interior and exterior—unlike corrosion-prone steel tanks.
  • Consistent weight.
  • Thick, damage-resistant walls.
  • Available in various painted and unpainted finishes.

1 Aqua-Lung, Aqua Lung and Aqualung are registered trademarks of Aqua Lung International and Aqua Lung America, divisions of Air Liquide. Co-inventor of the original Aqua-Lung was Emile Gagnan.
2 It is the responsibility of the cylinder owner to maintain Nitrox suitability by keeping the cylinder cleaned and prepared for use with oxygen and oxygen-rich gas blends in accordance with regulations in effect in the country in which the cylinder is being used and by using only oxygen-compatible components with Luxfer cylinders in oxygen and oxygen-enriched applications.

Product: L6X® aluminum cylinder specifications

In 1988, Luxfer introduced scuba tanks manufactured from L6X®, a proprietary formula of aluminum alloy 6061-T6 developed by Luxfer metallurgists to provide superior corrosion- resistance and dependable performance in the most demanding underwater environments.

Compared to conventional alloys, L6X has been optimized to improve durability, fracture toughness and resistance to cracking and tearing, even under high pressures over long periods. More than 50 million Luxfer cylinders manufactured from L6X alloy have an exemplary record for safety, long service life and reliable performance.
