The Honda 91370-SP0-003 O-Ring (6.8X1.9) is a genuine OEM sealing component designed for H5013, H5518, and RT5000 multi-purpose tractors. As a direct Honda OEM part, this o-ring is manufactured to the exact dimensions and material specification required for a proper seal in these machines. Confirm your tractor's serial number against the fitment table before ordering, as Honda supersedes sealing components at production breaks and dimensional tolerances are critical. DHS Equipment supplies this part direct, so you can be confident you are getting the correct Honda component.
Key Features
- Exact Dimensional Fit — at 6.8 mm inner diameter and 1.9 mm cross-section, this o-ring matches the precise groove geometry Honda specifies for these tractors; an undersized or oversized ring will not seat correctly
- Genuine Honda OEM — sourced directly from Honda, carrying part number 91370-SP0-003, so there is no guesswork about whether the ring's compound and sizing meet the original design intent
- Tractor Compatibility — listed for H5013, H5518, and RT5000 multi-purpose tractors; check your serial number against the fitment table to confirm the correct application for your unit
- Sealing Integrity — a correctly installed, properly sized o-ring maintains the fluid or pressure boundary it is designed to hold; a worn, cracked, or wrong-sized ring allows leaks that can lead to fluid loss and component damage over time
An o-ring is a loop-shaped sealing element seated in a machined groove between two mating surfaces or around a shaft, port, or fitting. When compressed at assembly, the ring fills the gap between surfaces and prevents fluid or air from passing through. In multi-purpose tractors like the H5013, H5518, and RT5000, o-rings appear throughout hydraulic circuits, fluid passages, and fittings where a reliable, leak-free seal is essential to safe and consistent tractor operation. When an o-ring hardens, cracks, or deforms with age, the seal it creates breaks down, causing leaks that rob the system of pressure or fluid and can quickly escalate into larger mechanical problems if left unaddressed.
