The Honda 91309-Z6L-000 O-Ring (37.9X2.4) is a genuine OEM sealing ring designed for a wide range of Honda horizontal shaft engines, generators, and two-stage snow blowers, including GX240, GX270, GX340, GX390, GX630, GX660, GX690, GX700, GX800, EB3800, EB4000, EB5000, EB6500, EB10000, EM3800, EM4000, EM5000, EM6500, HS1336, and HSM1336 models. Sourced directly from Honda, this O-ring matches the exact dimensions and material grade Honda specifies for this application. Verify your model and serial number against the fitment table before ordering, as Honda revises part assignments at production breaks across this wide range of equipment.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Honda's exact dimensional specification (37.9 x 2.4 mm) so the ring seats correctly and delivers a consistent, leak-free seal in its intended bore or port.
- Broad Honda Compatibility — listed for GX-series horizontal shaft engines, EB and EM generators, and HS1336 and HSM1336 two-stage snow blowers, making this a widely used OEM sealing component across Honda's commercial lineup.
- Direct Drop-In Replacement — as an OEM part, this O-ring installs in place of the original with no trimming or adaptation; the 91309-Z6L-000 part number confirms an exact catalogue match.
- Serial Number Verification Recommended — Honda updates sealing components at production serial breaks, so always confirm your unit's serial number against the compatibility table to ensure this is the correct ring for your machine.
An O-ring is a precision loop seal that sits in a machined groove and compresses against a mating surface to prevent fluid or air from passing between two joined components. When an O-ring hardens, cracks, or takes a set from heat and age, it loses its ability to maintain a seal, which can result in oil leaks, coolant loss, or pressure loss depending on the system it is serving. Replacing a worn O-ring with the correct OEM part — matched by part number 91309-Z6L-000 — restores a tight, reliable seal and prevents the progressive fluid loss or contamination that a compromised ring allows.
