O-RING (Yale YT190580)

A degraded O-ring can allow fluid or gas to escape from a sealed connection. This aftermarket replacement part references Yale as the OE maker and cross-references part number YT190580. The O-ring functions as a deformable seal that compresses between two mating surfaces to prevent leakage. A common failure mode is hardening or cracking, which leads to loss of sealing pressure and potential system contamination. Keeping an O-ring in pliable condition helps maintain consistent sealing force under varying temperatures. Verify the serial number or application, then call (562) 693-7748. This catalog listing is for a retaining ring category component.
