The Honda 91601-ZE1-821 Gasket is a genuine OEM replacement designed for GXV270 and GXV340 vertical shaft engines as well as Honda HS-series two-stage and single-stage snow blowers, including the HS520, HS521, HS621, HS55, HS80, HS828, HS928, HS1132, and HS1332. As a direct OEM part sourced from Honda, this gasket matches the original specification exactly, ensuring a proper seal without trimming or modification. Verify your unit's serial number against the fitment table before ordering, as Honda supersedes gaskets at serial breaks across these model lines.
Key Features
- Genuine Honda OEM Sealing — manufactured to the same specification as the original, delivering the correct material density and compression characteristics required for a lasting seal on these engines and snow blowers.
- Broad Model Coverage — listed for GXV270 and GXV340 vertical shaft engines and Honda HS-series snow blowers including the HS520, HS521, HS621, HS55, HS80, HS828, HS928, HS1132, and HS1332.
- Serial Number Verification Recommended — Honda updates gasket part numbers at production breaks, so confirm your machine's serial number against the fitment table to ensure this is the correct gasket for your unit.
- Direct OEM Replacement — this gasket replaces the original part for a straightforward service repair with no custom fitting required.
A gasket creates a controlled, leak-free seal between mating surfaces in an engine or mechanical assembly. It compensates for minor surface irregularities and maintains that seal under the heat, pressure, and vibration of normal operation. When a gasket deteriorates, compresses unevenly, or fails outright, the result is leakage — whether of oil, air, or exhaust gases — that leads to poor performance, contamination, or accelerated wear on surrounding components. Replacing a worn or damaged gasket with the correct OEM part restores the integrity of that joint and keeps the engine or equipment operating as intended.
