The Honda 91373-733-003 O-Ring (45.5X2.5) is a genuine OEM seal designed for Honda F401, F501, FC600, FG400, and FG500 tillers. As a direct Honda OEM component, this O-ring is manufactured to the exact dimensions and material specification required for a proper seal in these machines. Verify your tiller's model and serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and the correct listing matters.
Key Features
- Genuine OEM Seal Integrity — manufactured to Honda's exact dimensional specification, ensuring the sealing surface closes properly without gaps or distortion that a non-OEM ring can introduce
- Sized for the Application — the 45.5X2.5 designation identifies both the inner diameter and cross-section; matching these figures to your machine's service data is the most important step before installation
- Broad Tiller Fitment — listed for the F401, F501, FC600, FG400, and FG500 tillers, covering several models in Honda's tiller lineup
- Check Your Serial Number — Honda revises parts within a model run, so confirm your tiller's serial number against the compatibility table to ensure part number 91373-733-003 is the correct ring for your unit
An O-ring is a circular elastomeric seal that sits in a machined groove and compresses between two mating surfaces to prevent fluid or air from passing the joint. In Honda tillers, O-rings appear throughout the drivetrain, fuel system, and hydraulic or gear-oil circuits wherever two components must mate without leakage. When an O-ring hardens, cracks, or takes a permanent set, it loses the radial pressure that creates the seal, allowing oil or fuel to seep past the joint. Replacing a worn O-ring with the correct OEM part restores the tight seal that keeps fluids where they belong and prevents the contamination or fluid loss that can lead to accelerated wear inside the tiller.
