The Honda 91301-ZE1-821 O-Ring is a genuine OEM sealing component designed for GXV270 and GXV340 vertical shaft engines, as well as a wide range of Honda snow blowers including the HS521, HS621, HS55, HS80, HS828, HS928, HS1132, and HS1332. As a direct Honda OEM part, this O-Ring matches the exact profile and material grade specified for these applications, ensuring a proper seal at the installation point. Confirm fitment against your machine's serial number using the compatibility table before ordering, as Honda introduces part updates at specific serial breaks.
Key Features
- Genuine Honda OEM Seal — sourced directly from Honda, this O-Ring meets the exact dimensional profile required to form a reliable seal in GXV270, GXV340, and HS-series applications.
- Direct Drop-In Replacement — matches the original part's cross-section and durometer, so installation requires no modification to the surrounding hardware.
- Broad Fitment Coverage — listed for GXV270 and GXV340 vertical shaft engines, plus HS521, HS621, HS55, HS80, HS828, HS928, HS1132, and HS1332 two-stage and single-stage snow blowers; check your serial number against the fitment table to confirm the correct application.
- Leak Prevention — a degraded or damaged O-Ring allows fluid or air to bypass the seal, leading to leaks and potential performance loss; replacing it promptly keeps the system sealed and operating correctly.
An O-Ring is a circular elastomeric seal that sits in a machined groove, compressing between two mating surfaces to prevent the passage of fluids or gases. In engines and power equipment, O-Rings are used throughout fuel, oil, and cooling circuits to maintain pressure and prevent leaks at joints, ports, and covers. When an O-Ring hardens, cracks, or deforms with age and heat cycling, it loses its ability to seal, allowing leaks that can lead to fluid loss, contamination, or reduced system efficiency — making timely replacement essential to keeping the equipment running correctly.
