Flux-Cut® head cylinder for gear of the 2nd and 3rd version. Made with the CNC machining, it has a larger cone diameter designed to fit perfectly to the piston one, with a much more pronounced angle. It presents only one o-ring seal but larger. In addition two abutment o-ring have been applied, in front and rear position, designed to ensure that the surface of impact between the two heads is low, and its strength is much more softer, also the particular shape of holes are designed to use the front O-ring part and soften up the impact and extend the life of the gearbox.
