StrongArm gas springs use a patented triple-lobe piston rod seal designed to prevent gas leakage and to extend product life. Designed to exceed industry standards, StrongArm can be pressurised with nitrogen gas up to 563 N (2,500 PSI). Most applications require only 338 N (1,500 PSI). StrongArm gas springs are also designed to operate in temperatures extremes ranging from -40°C to 80°C.
StrongArm gas springs are continually monitored during the assembly process to verify the correct pressure for each unit. After assembly, each gas spring is tested in four different positions during compression and extension to measure speed and force. Each lift is then subjected to two overload tests to assure structural integrity and safety.
