Below is a list of Tension Gas Springs manufacturers from Melbourne, Florida. Tension gas springs are one of two major categories of gas springs that are pneumatic energy storage devices, which employ compressed gas in order to provide shock absorption, damping or the exertion of force. These devices are designed to remain in the tensed or closed position. To compare to mechanical coil springs, the relaxed state of these springs would be when the many coils are close together with no gaps between them.
