PVC pneumatic cylinder

Turn on the subtitles for more information.
This is a simple action compressed air cylinder. It was the first one I made, still lacking features to replace a normal cylinder, but so far it has worked perfectly well and without leaks.
The tests were done with compressed air at a pressure of only 3 bar (44 psi). These PVC pipes are rated for up to 7.3 bar (106 psi), but I don't trust PVC pipes holding such pressures.
