XS Scuba Gas Cylinders offers a broad range of high-pressure aluminum scuba cylinders.
More than 50 years ago, XS Scuba developed the world’s first aluminum scuba cylinder in collaboration with the legendary Jacques-Yves Cousteau, inventor of the original Aqualung equipment that revolutionized underwater diving.
In 1988, XS Scuba introduced scuba tanks manufactured from L6X, a proprietary formula of aluminum alloy 6061-T6 developed by XS Scuba 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 XS Scuba cylinders manufactured from L6X alloy have an exemplary record for safety, long service life, and reliable performance.
