1. Are you replacing an existing gas strut, or selecting gas struts for a new installation?

Gas Strut Safety - Read Before Removal or Installation

  • Always independently support the lid, hatch, door or panel before removing or installing a gas strut. Never work beneath a panel supported only by gas struts.
  • Gas struts contain pressurised gas and stored energy. Do not drill, puncture, cut, crush, weld, open or deliberately damage a pressurised gas strut. Follow the manufacturer's disposal instructions.
  • Do not expose gas struts to excessive heat, flame or conditions outside the manufacturer's specified operating limits.
  • Do not install or reuse a strut that is bent, dented, badly corroded, leaking, mechanically modified or otherwise damaged.
  • Avoid scratching, painting, greasing, contaminating or damaging the piston rod.
  • Do not subject the strut to side-loading, bending or misalignment. Existing mounting points and fittings must allow the strut to move freely without binding.
  • Do not exceed the intended stroke or use the strut as a mechanical end stop unless the original application was designed that way.
  • Keep hands and body parts clear of hinges, brackets, pinch points and moving panels during removal and installation.
  • If the existing specifications cannot be positively identified, the replacement does not match, or you are unsure about safe removal or installation, stop and seek professional assistance.
Catalogue dimensions and availability can change. This finder uses the current working range established for Trailer Parts Direct and the specifications entered by the customer.
