The Honda 91301-PC9-003 O-Ring (7.7X2.3) is a genuine OEM sealing component designed for B75 portable outboard motors and H6522 compact tractors. As a direct Honda OEM part, it is manufactured to the exact dimensions Honda specifies for these machines, ensuring a proper seal where it is installed. Because this O-Ring is listed for two distinct machine types, confirm your serial number against the fitment table to ensure part number 91301-PC9-003 is the correct application for your unit.
Key Features
- OEM Sealing Integrity — molded to Honda's exact 7.7 x 2.3 mm dimensions, delivering the consistent compression and fluid retention a genuine O-Ring provides
- Direct OEM Replacement — sourced directly from Honda, this O-Ring matches the original specification without modification or adjustment
- Broad Fitment Coverage — listed for B75 portable outboard motors and H6522 compact tractors; verify your serial number against the fitment table before ordering
- Sealing Consistency — a correctly seated O-Ring prevents fluid or pressure loss; a worn or deformed ring allows leaks that can lead to operational issues in either machine
An O-Ring is a circular elastomeric seal designed to sit in a machined groove and compress between two mating surfaces, blocking the passage of fluids or gases under pressure. In both outboard motors and compact tractors, O-Rings are used throughout fluid circuits — including fuel, oil, and cooling passages — where a reliable, leak-free seal is essential to keeping the machine running correctly. When an O-Ring hardens, cracks, or loses its shape, the seal fails and fluid can escape, making timely replacement important to maintaining proper operation.
