Key Features
- OEM Material and Compression Rating — Manufactured to the exact material grade and thickness specified by Multiquip, ensuring proper sealing pressure and resistance to heat and fluids in Honda-powered generator applications.
- Direct Drop-In Fit — Matches the original bolt pattern, port openings, and surface profile for a flush, leak-free installation without trimming or adapting.
- Broad Generator and Welder Coverage — Fits GA6HB, GA6HEB, GA6HR, GA6HRS, GA6HRSNC2, GA3.6HR, GAC3.6HR, GAC6HR, GAC6HRS, GAW180HE, GAW180HEA, and GAW180HE1 models.
- Leak Prevention at Critical Joints — A correctly seated gasket maintains compression and prevents oil, fuel, or exhaust gases from escaping at mating surfaces, protecting both output consistency and engine longevity.
- Genuine OEM Part — Supplied by Multiquip under part number 18333ZB4801, giving you the same component used in original production and authorized service repairs.
A gasket creates a pressure-tight, fluid-tight seal between two mating surfaces — such as an engine cover, carburetor flange, or exhaust port — preventing gases and liquids from leaking out at joints that experience heat and vibration. In a generator or welder application, a compromised gasket can cause oil or fuel leaks, loss of compression, and erratic engine performance that affects power output quality. Replacing a worn or damaged gasket with a correctly specified OEM part restores the integrity of that sealed joint and keeps the engine running at its rated output.
