Fuel pump O-ring 62.5x3 320/06868 JCB Dieselmax, aftermarket

Fuel pump O-ring 62.5x3 320/06868 is an aftermarket part for the JCB Dieselmax 444 engine.

An O-ring seals a round joint between two parts: it sits in a groove and is squeezed when the parts are assembled. A hardened, crushed or cut O-ring leaks. An O-ring is defined by its inside diameter, cross-section and material; the wrong size or material soon fails. The O-ring is always renewed when a joint is taken apart. The O-ring is made of rubber that withstands the fluid and temperature of its joint.
