Piston head & cylinder head set by Element. It is for gearboxes v.3.
The piston head is made of light, yet durable POM. The impact is silent thanks to the rubber front side of the head. There's a ball bearing on the rear side. A spring has a tendency to rotate when compressing and the bearing allows the spring to rotate, so the compressing process is smoother.
The cylinder head is made of brass and it has one sealing o-ring and a rubber pad. This head is shaped for being used together with that Element piston head.
