F1 = the extendible force measured at 5 mm inward piston rod.
The piston rod is hard chromium plated and the cylindertube is zink plated.
Other lengths, max. forces and screwthreads on request.
This type of gasspring is a more advanced type of our force releasable gasspring. When turning the valve slowly by means of an allen key clockwise, a small quantity of air will escape. These gas springs only drop a small measured amount of pressure and can never loose all pressure at once. When using more than one gasspring and the same number of turns all gassprings will retain the same force.
These gassprings can of course be topped up, if more pressure is needed.
