Our L7X all-metal oxygen cylinders are manufactured from Luxfer's higher-strength L7X aluminum alloy.
Luxfer L7X® Aluminum
Our L7X all-metal oxygen cylinders are manufactured from Luxfer's higher-strength L7X aluminum alloy. L7X advantages include higher-pressure filling up to 3,000 psi and significantly more gas capacity with no increase in cylinder size or noticeable weight gain.
Features and benefits:
- Same size and weight as conventional D-size cylinder with a 45 percent increase in oxygen capacity.
- Fewer swap-outs and less cylinder handling.
- Can be used with existing cylinder fleets.
- 30 percent lighter in weight than conventional steel cylinders.
- Manufactured in the USA.
Notes: All cylinders have non-limited service life as long as they pass required periodic testing.
