Pistons are H900 heat treated with a rust inhibitor. Please note, color and color pattern will vary due to the heat treatment.
It is important to intermittently clean and lubricate the exterior of the piston and interior of the booster housing to ensure smooth reciprocation with the O ring in the piston retainer.
O-Rings should be replaced intermittently when worn to ensure alignment of the silencer with the booster assembly. Failure to replace damaged or worn O-rings could result in a baffle strike or damage to the piston components.
