CNC Cylinder head B - exhaust length 25.8mm
New universal cylinder head for Gearboxes (Zinc and CNC) version II and version III. The cylinder head is made of aircraft duralumin EN AW 7075 by precision CNC turning and CNC milling. The cylinder head has an o-ring which ensures a precise seal between the cylinder head and the cylinder.
The cylinder head can be used with a standard straight piston head, but also with a silent piston head (not NBU, the cylinder head and piston head are designed for NBU).
The impact part of the cylinder head is made of extremely durable molded Polyurethane, which has several times more durability than vulcanized natural rubber.
