Gas Springs

A Gas Spring (sometimes refered to as a Gas Strut) comprises of piston and rod that slides up and down a pressurised sealed tube. The pressure of the inert fill gas can be varied to change the force required to move the piston and rod. Gas Springs are most commonly used as a counterbalance for raising and lowering doors and hatches. Typical applications are Car Hatch Backs, Luggage Compartments, Skylights and Machine Guards. The tube contains a small amount of oil to lubricate the rod and to control damping at the end of the stroke. Gas Springs should always be mounted with the rod downwards to prolong the active life.

Where possible, we advise the utilisation of 2 gas springs one at each end of the door to prevent twisting.
