Wolverine Airsoft O-Ring Kit – STORM Category 5
The Wolverine Airsoft O-Ring Kit for the STORM Category 5 is the replacement sealing O-ring set for Wolverine’s STORM Category 5 HPA regulator. The STORM Category 5 is a high-performance variant of the Wolverine STORM inline regulator family — designed for more demanding HPA applications where consistent regulated output under higher flow conditions is required. The regulator contains O-rings at the inlet, piston, and outlet positions. As these O-rings wear under repeated cycling and pressure, they degrade and allow air to bypass the sealed path — causing inconsistent output pressure, air leaks from the regulator body, or velocity creep between shots.
OEM Wolverine maintenance kit for STORM Category 5 regulator servicing. For STORM Category 5 users experiencing pressure inconsistency or regulator air leaks, replacing the O-rings with this kit is the correct first maintenance step for the Category 5 variant.
