Wolverine Airsoft O-Ring Kit – MAC Solenoid Valves
The Wolverine Airsoft O-Ring Kit for MAC Solenoid Valves is a replacement sealing O-ring set for the MAC brand solenoid valves used inside Wolverine HPA engines. MAC solenoid valves are the core airflow control component in Wolverine engines — they open and close to allow or block the HPA airflow that drives the firing cycle. The solenoid valve body contains multiple O-rings that seal the valve against air leaks between the inlet, outlet, and exhaust ports. Over time and operating cycles, these O-rings can harden, deform, or crack — resulting in air leaks from the solenoid, inconsistent cycling, reduced shot count, or engine stalls.
Replacing the O-rings in the MAC solenoid valve is a standard maintenance procedure for Wolverine engine operators. This kit contains the correct O-ring sizes for the MAC solenoid valve used in Wolverine engines. For Wolverine operators experiencing solenoid air leaks or cycling inconsistency, replacing the solenoid O-rings is the correct first-step repair.
