The Caterpillar NBR (90) O-Ring (3K-0360) 3K0360 is an essential component used to seal fixed and moving parts. Made from materials that are specifically compatible with Cat engines and machines, these O-rings offer high resistance to wear and deformation. They also provide excellent resistance to compression and are dimensioned to close tolerances for optimal performance.

Some Cat O-rings are coated with polyurethane to increase resistance to twisting and damage during installation. With its parallel thread design (STOR), this O-ring is suitable for a variety of applications including ambient temperature fuel systems, LPG auxiliary systems, hydraulic fluids, power steering system seals, and radiator thermostat seals.
