The Honda 91307-PH7-660 O-Ring (13.5X1.4) is a genuine OEM replacement seal designed for a wide range of Honda outboard motors, generators, horizontal shaft engines, lawn tractors, and RV generators. As a direct Honda OEM component, this O-ring is manufactured to the exact dimensions and durometer required for proper sealing across all listed applications. This O-ring is listed for equipment including BF25 and BF30 outboard motors, the GX360 horizontal shaft engine, EM5000, EB12, EL5000, ES6500, and EX5500 generators, EV4010, EV6010, and EVD4010 RV generators, and H4514, H4518, HT3813, and HT4213 lawn tractors, as well as the H5518 multi-purpose tractor — always verify your unit's serial number against the fitment table to confirm this is the correct listing for your machine.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Honda's exact 13.5 x 1.4 mm dimensions, ensuring the cross-section and durometer match what Honda specifies for a leak-free seal in each application.
- Broad Cross-Catalogue Fitment — listed across Honda outboard motors, generators, RV generators, horizontal shaft engines, lawn tractors, and multi-purpose tractors, including BF25, BF30, GX360, EM5000, and EV4010 among others.
- Verify by Serial Number — Honda supersedes sealing components at production breaks; confirm your machine's serial number against the fitment table before ordering to ensure part number 91307-PH7-660 is correct for your unit.
- Direct OEM Replacement — sourced from Honda's own parts catalogue, this O-ring installs directly in place of the original with no modification needed to the seating groove or mating surfaces.
An O-ring is a loop-shaped elastomeric seal that sits in a machined groove between two mating surfaces or around a shaft or fitting. When the joint is assembled, the O-ring is compressed slightly, creating a pressure-tight barrier that prevents fluid or gas from escaping the sealed passage. In engines, generators, outboard motors, and tractors alike, O-rings are found throughout fuel systems, oil circuits, and cooling passages. When an O-ring hardens, cracks, or takes a permanent set, the seal is lost — leading to fluid leaks, loss of pressure, or contamination that can cause broader component damage if left unaddressed. Replacing a worn O-ring with the correct genuine Honda part restores the original sealed condition and protects the surrounding components.
