CNC Aluminum Cylinder Head – Type B (Universal)

New universal cylinder head for gearboxes (Zinc and CNC) version II and version III and others from RetroArms. The cylinder head is made of aviation-grade duraluminum EN AW 7075 through precise CNC turning and CNC milling. The cylinder head has a sealing O-ring that ensures precise sealing between the cylinder head and the cylinder.
The cylinder head can be used with both standard flat piston heads and silent piston heads (not NBU, for NBU, a specific cylinder head and piston head are intended).
Impact part of the cylinder head is made of extremely resilient cast Polyurethane, which has a significantly longer lifespan than vulcanized natural rubber.
