Honda 91314-ME5-003 O-ring 10x2.6mm

Product Description

The HONDA 91314-ME5-003 is an OEM replacement O-ring sized at 10x2.6mm, designed to create a leak-free seal at fluid or air connections in Honda powersport and small-engine applications. This ring seats into a precision machined groove to prevent fluid bypass and maintain system pressure integrity. Installation is performed by licensed technicians or qualified small-engine mechanics during routine service or component replacement. Its compact profile and consistent cross-section ensure proper compression and seal retention over repeated thermal cycles.

This O-ring is used in sealing applications across Honda motorcycles, powersport equipment, and related small-engine platforms where fluid containment at threaded fittings, housings, or covers is required. It is a direct OEM part suitable for use in any service scenario calling out part number 91314-ME5-003. Technicians servicing fuel systems, oil passages, or coolant circuits should verify groove dimensions match the 10x2.6mm specification before installation.

Installation Notes

Always depressurize and drain the relevant fluid circuit before removing the old O-ring. Clean the seating groove thoroughly to remove debris or residual sealant before seating the new ring. Lubricate the O-ring lightly with a compatible fluid or assembly lubricant prior to installation to prevent pinching or rolling during reassembly. Follow the applicable Honda service manual torque sequence when reinstalling the mating fasteners or housing.
