The Yale CMY-1 is the standard male coupler half supplied on Yale 700 bar hydraulic hoses. The self-sealing design uses inner balls to seal the coupler in un-coupled condition. The CMY-1 has 3/8 NPT inner thread, matching the standard CFY-1 female coupler.
Standard male coupler half on Yale hoses
Yale documentation specifies the CMY-1 as the standard male coupler half supplied on all Yale HHC hydraulic hoses. The self-sealing mechanism uses inner balls so the coupler halves only need to be closed hand tight. Both female (CFY) and male (CMY) coupler halves have inner balls that prevent hydraulic fluid leak in un-coupled condition.
Suitable Applications
Per Yale: standard male coupler on all Yale HHC hydraulic hoses. Spare or replacement on damaged hose ends.
Every part of the circuit carries a pressure rating, and the system is limited by its lowest-rated component — check these against the pump and cylinder in use.
