Our standard Tension Gas Spring (T) has a hard chrome plated rod for durability and smooth operation, however if this rod becomes damaged or bent it could lead to premature seal wear and a shorter lifespan. If your application is in a dusty/dirty environment, likely to suffer impacts to the rod or of a particularly long stroke length then it is advisable to use a Protected Tension Gas Spring (TP).
