O-RING (Yale YT18974)

A damaged O-ring can allow fluid or gas to escape from a sealed connection, leading to system inefficiency or component wear. The Yale catalog reference for this aftermarket replacement part is YT18974. This O-ring type creates a static seal between two mating surfaces to prevent leakage. A common failure consequence is gradual loss of pressure, which may reduce operational reliability. During routine service, a hardened or cracked O-ring often requires replacement to restore sealing integrity. The part is constructed from a resilient elastomeric material suited for its sealing application. Verify the serial number or application, then call (562) 693-7748.
