Key Features
- Genuine OEM Sealing Performance — Honda-original construction delivers the dimensional consistency a sealing washer depends on to form a leak-free joint rather than an approximate one.
- Exact Dimensional Spec — the 6.2 x 12 x 1.2 mm profile matches Honda's original design, allowing this washer to drop in without rework or shimming.
- Broad Honda Fitment — listed for FR-series tillers, GXV140 and GXV160 vertical shaft engines, and multiple HR-series lawn mowers including the HRC216, HRM215, and others.
- Verify by Serial Number — Honda supersedes hardware at production breaks, so check your machine's serial number against the fitment table before ordering to confirm this is the correct washer for your unit.
A sealing washer serves a straightforward but critical role: it forms a fluid-tight seal under a fastener or fitting, preventing oil, fuel, or other fluids from leaking past the joint. Unlike a plain flat washer, the sealing washer's controlled thickness and diameter work together with the clamping load of the fastener to compress against the mating surface. When this washer is worn, deformed, or missing, seepage can develop at that joint, leading to fluid loss and the contamination or mess that follows. Replacing it with a dimensionally correct OEM part restores the seal as Honda originally intended.
