Wolverine Airsoft O-Ring Kit – HAVOC
The Wolverine Airsoft O-Ring Kit for HAVOC is the complete O-ring replacement set for the Wolverine HAVOC HPA pistol engine. The HAVOC is Wolverine’s dedicated HPA pistol engine, designed for conversion of GBB-format pistols to HPA operation. Like all HPA engines, the HAVOC contains multiple O-rings at the piston, nozzle, and valve positions that maintain the sealed air path. These O-rings degrade with cycling — hardening, cracking, or deforming to create air leaks, velocity loss, and cycling failures. The HAVOC O-Ring Kit contains the correct sizes for all positions in the HAVOC engine for a complete maintenance service in one pass.
OEM Wolverine maintenance kit for HAVOC engine servicing. For HAVOC engine operators experiencing air leaks or declining velocity from their HPA pistol platform, this kit is the correct complete O-ring set for the HAVOC engine.
