ADAPTER- ST S JIC/ORB (Yale YT201779)

A damaged adapter can cause fluid leaks that reduce system pressure and lead to component wear. During inspection, an adapter of this type connects two different thread configurations—straight thread (ST) and JIC/ORB—to maintain a sealed joint. Keeping an adapter in sound condition helps prevent contamination ingress at the connection point. The part is an aftermarket replacement referencing the Yale catalog number YT201779. Its general function is to transition between thread styles while withstanding typical operating pressures. A common failure consequence is a gradual drip that wastes fluid and attracts debris. Verify the serial number or application, then call (562) 693-7748.
