  • L6X® aluminum SCBA cylinder

    L6X® aluminum SCBA cylinder

    Up to 40 percent lighter in weight than comparable steel cylinders.

Luxfer's all-aluminum SCBA and life-support cylinders have been the industry workhorse in North America since the early 1970s. Since 1988, Luxfer has manufactured these cylinders from its own proprietary version of 6061-T6 alloy. Now marketed as L6X®, this exclusive aluminum-magnesium-silicon formula was specifically designed by Luxfer metallurgists. More than 40 million L6X all-metal and composite cylinders in service around the world have an exemplary record for safety and dependability.

Features and benefits:

  • Up to 40 percent lighter in weight than comparable steel cylinders.
  • Luxfer aluminum SCBA cylinders are non-magnetic and extremely corrosion resistant.
  • Improved durability, fracture toughness and resistance to tearing and cracking.
  • Manufactured in the USA.

Notes: All cylinders have non-limited service life as long as they pass required periodic testing. All cylinders are certified to DOT-3AL/TC-3ALM.
