Lonex POM piston head - ventilated

Made from durable polyacetal, the Lonex POM piston head is suitable for almost all tuning levels and is very durable even in high-performance configurations. In this ventilated piston head, air vents expand the O-ring for optimal air tightness. Ball bearings enhance the action of the progressive spring.

A piston head made of polyacetal (POM) is more durable than a piston head made of polycarbonate/nylon. In addition, a POM piston head is lighter than a metal one and puts less strain on the gearbox and the mechanism than a metal piston head.
