Product Overview
This high-quality Original O-Ring 31.2X2.4 is designed to meet or exceed factory performance standards and is suitable for Honda PCX 125 (2021-2024) models.
The O-Ring 31.2X2.4 is a precision-dimensioned circular sealing ring used in the engine assembly to create a reliable oil-tight and fluid-tight seal between mating components, preventing leaks at critical engine joints. Over time, heat cycling and compression cause the rubber O-Ring to harden, lose its elasticity, or develop flat spots, breaking the seal and allowing engine oil to seep from the joint, leading to external leaks, oil loss, and potential contamination of surrounding components. This original replacement restores the original sealing integrity at the engine joint, ensuring seamless, secure, and reliable operation of your PCX 125.

Complete Part Guide
The 31.2X2.4 O-Ring is a vital sealing component for the 2021-2024 Honda PCX125, specifically designed for high-temperature engine interfaces. A damaged O-Ring leads to persistent fluid weeping or air leaks, which can contaminate other drivetrain parts and lead to a drop in internal pressure. This original Honda part (91303-K0R-V01) is specially engineered to resist chemical degradation and heat. In stock at Part Hive's London warehouse, complete your orders before 1 PM for guaranteed same-day UK dispatch.
We often see 2021-2024 Honda PCX-125s with "mysterious" oil weeping or cooling system pressure loss, frequently traced back to a crushed 91303-K0R-V01 O-Ring. In the heavy stop-start environment of North London, constant heat cycles cause standard rubber to lose its elasticity. This original Honda O-Ring features exact dimensions (31.2mm x 2.4mm) that are critical for a rattle-free, pressurized fit. Installing this original seal ensures the assembly remains bone-dry and maintains the vacuum integrity needed to prevent intermittent idling issues and power fluctuations.
