    L7X® Aluminum

    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.

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.
