Below is a list of Gas Springs manufacturers from Carp, Ontario. Gas springs are pneumatic energy storage devices that utilize high pressure gas housed within a cylinder for a number of practical applications, which always involve shock absorption, damping or the exertion of force by way of the gas filled cylinder. The basic function is very similar to air cylinders in that a piston is either compressed or extended based on the pressure differential between the gases within the chamber and those acting upon its exterior.
