RING - SEAL (Komatsu KO3EB-15-11240)

A worn seal ring can allow fluid leakage, reducing system pressure and causing erratic operation. This aftermarket replacement part references Komatsu as the OE maker and carries the cross-reference number KO3EB-15-11240. The ring functions as a static or dynamic seal, preventing fluid bypass between mating surfaces. A common failure consequence is gradual loss of sealing integrity, leading to contamination ingress or external drips. During routine service, a seal ring may appear hardened or cracked from age or heat exposure. Verify the serial number or application, then call (562) 693-7748.
