The Honda 90441-286-000 Sealing Washer (8MM) is a genuine OEM replacement designed for H5013 multi-purpose tractors, HR17 lawn mowers, and RT5000 multi-purpose tractors. As a direct Honda OEM component, this sealing washer is sourced and supplied to Honda's own specifications, giving you confidence that it will seat and seal correctly in your machine. Confirm your model and serial number against the fitment table before ordering, as Honda supersedes hardware at production breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this washer meets the exact dimensional and sealing requirements of the original hardware it replaces.
- Correct 8MM Size — the (8MM) designation identifies the specific variant; match this to your machine's specification before purchasing.
- Broad Fitment — listed for the H5013 and RT5000 multi-purpose tractors and the HR17 lawn mower, including select production ranges across those models.
- Check Your Serial Number — Honda updates hardware part numbers at serial breaks, so verify your machine's serial number against the compatibility table to confirm this is the correct washer for your unit.
A sealing washer is a small but important piece of hardware used to create a fluid-tight or fastener-securing seal at a bolted joint. The washer's design allows it to deform slightly under clamping load, filling minor surface irregularities and preventing fluid seepage or fastener loosening at that connection point. When a sealing washer fails, degrades, or is left out during reassembly, the joint it sits at can develop a leak or allow a fastener to work loose over time.
