CUP, Check Valve, for Hunter. RP6-0718

 

The air hoses connect to the air motor through a double check valve (one for each hose) assembly mounted on the bottom of the air motor. This valve prevents air escaping through whichever hose is not pressurized. If one or both of the cups are bad, the motor will work in only one direction, not work at all, or lack power. 

 

Found on Hunter models: TC-150, TC-250, TC-300, TC-325, TC-350, TC-3250, & TC-3500.
