O-RING (Yale YT18942)

A degraded O-ring can cause fluid leaks that compromise system pressure. This aftermarket replacement part references Yale as the OE maker and cross-references part number YT18942. The O-ring functions as a static seal between mating surfaces to prevent fluid bypass. A common failure mode is hardening or cracking, which leads to gradual seepage and eventual loss of sealing integrity. In applications where consistent sealing is critical, a deteriorated O-ring may allow contamination ingress. Verify the serial number or application, then call (562) 693-7748. This catalog listing is for a retaining ring category component.
