The Multiquip 12312ZM3020 is a genuine OEM Gasket Head Cover GX22/31 HC- designed for GX22 series equipment.

Fitment is confirmed for GX22 applications, so you can install with confidence and get your equipment back to work without guesswork.
Key Features
- Genuine OEM Sealing Material — Manufactured to the precise compression rating and material grade required for the GX22/31 head cover interface, ensuring a consistent, leak-free seal.
- Direct Drop-In Replacement — Matches the original head cover profile exactly, seating flush against mating surfaces without trimming or reworking.
- Confirmed GX22 Fitment — Validated for GX22 series engines, eliminating compatibility uncertainty before you begin the repair.
- Prevents Oil Leaks and Contamination — A worn or degraded head cover gasket allows oil to seep past the cover joint; this replacement restores the positive seal that keeps oil inside and contaminants out.
- Fuel and Oil System Safety — A correctly seated head cover gasket prevents oil from migrating toward ignition or exhaust components, maintaining safe operating conditions on the engine.
The head cover gasket forms the sealing barrier between the valve cover and the engine block, preventing oil from escaping around the top of the engine. It must compress evenly at the correct torque to maintain a consistent seal through heating and cooling cycles. When the gasket deteriorates, hardens, or cracks, oil leaks develop at the head cover joint — leading to oil loss, potential engine damage, and a fire risk if oil contacts hot exhaust surfaces. Replacing it with a correctly specified OEM gasket restores the seal and protects the engine's long-term integrity.
