The Honda 91363-VD6-900 O-Ring (6.8X1.9) is a genuine OEM replacement built for HR215 and HRC216 lawn mowers. As a direct Honda OEM component, this o-ring is produced to the exact dimensional specification the engineers originally called out — 6.8 mm inside diameter with a 1.9 mm cross-section — ensuring a consistent, leak-free seal in its intended application. Confirm your mower's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this listing covers specific production ranges of the HR215 and HRC216.
Key Features
- Exact OEM Dimensions — manufactured to Honda's specified 6.8 x 1.9 mm profile, so this o-ring seats and seals the same way as the original every time
- Genuine Honda Part — sourced directly from Honda's OEM supply chain, not a generic substitute; part number 91363-VD6-900 is the correct catalogue reference for these mowers
- Mower-Specific Fitment — listed for the HR215 and HRC216 Honda lawn mowers; check your serial number against the compatibility table to confirm the right production range
- Sealing Integrity — a correctly sized o-ring maintains a fluid-tight joint and prevents leaks that can lead to loss of performance or fluid contamination in the mower's systems
An o-ring is a circular elastomeric seal used wherever two mating components must be joined without allowing fluid or air to pass between them. In a lawn mower, o-rings appear in fluid circuits and threaded or press-fit joints throughout the machine, and their small size makes precise dimensional conformity critical — even a slight deviation in diameter or cross-section can compromise the seal. When an o-ring ages, hardens, or takes a compression set, it loses the elasticity needed to fill the joint, and leaks or pressure loss follow.
