DMAC Silenced X-Flow ® Piston Head

Silenced Piston head made with CNC machining. Thanks to the implementation of the abutment o-ring, the sound will be lowered by making the ASG very silent,

The shape of the front part of the REDPOWER piston head has been studied to further reduce the stress due to the impact with the cylinder head PAD even at R.O.F. elevated. The REDPOWER head does not have the double sealing/centering O-RING, but has a small recess that decreases the contact surface with the inside of the cylinder, to reduce friction to a minimum. The total height of the TopMax piston head is standardized to the dimensions of the other piston heads on the market. The ERGAL and DELRIN insert for fixing the piston head on the piston is slightly shorter than the standard market size, in order to use the TopMax piston head on any piston on the market.
