F1 = the extendible force measured at 5 mm inward piston rod.
The piston rod is made of stainless steel AISI 316 or AISI 431 hard chromium plated, and the cylinder is made of stainless steel AISI 316 and grinded.
The botompiece and the guiding are made of seaworthy bronze.
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.
