The Honda 91312-107-000 is a genuine OEM O-Ring (7X1.7) designed for the F28 tiller. As a direct Honda OEM component, this o-ring is manufactured to the exact dimensions required for a proper seal in the F28. When an o-ring wears, cracks, or takes a set, it can no longer maintain a proper seal, leading to fluid leaks and potential damage to the equipment — replacing it with the correct Honda part keeps the F28 running as intended.
Key Features
- Genuine Honda OEM Seal — sourced directly from Honda, this o-ring meets the exact dimensional specifications required for effective sealing in the F28 tiller
- Exact Dimensional Fit — the 7x1.7 mm profile matches the original groove and bore, ensuring the part seats and seals correctly without modification
- Leak Prevention — a correctly functioning o-ring maintains a fluid-tight seal; a worn or hardened original allows seepage that can compromise tiller operation
- Verify Your Serial Number — Honda updates parts at production breaks, so confirm your F28 serial number against the fitment table before ordering
An o-ring is a simple but essential loop-shaped seal, sized precisely in diameter and cross-section to fill a machined groove between two mating surfaces or around a shaft or fitting. When properly seated, it is compressed just enough to block the passage of fluid or air. Over time, heat cycling, chemical exposure, and mechanical stress cause the rubber to harden, crack, or permanently deform — at which point it can no longer maintain a positive seal. Replacing a failed o-ring with the correct Honda OEM part, matched exactly by size and compound, restores the original sealing performance and prevents leaks from developing into more serious mechanical issues.
