Yale CFY female coupler halves are self-sealing quick-connect couplers rated for 700 bar. Yale specifies the design with inner balls that seal the coupler halves in un-coupled condition, preventing hydraulic fluid leakage. The CFY range covers four thread variants: CFY-1 (3/8 NPT outer - standard), CFY-2 (3/8 NPT inner), CFY-18 (M18 x 1.5 outer), CFY-10-S (Pipe Ø 10 mm).

Standard female coupler half supplied with all Yale cylinders

Yale specifies that all Yale hydraulic cylinders are equipped with the standard female coupler half CFY-1 and dust cap CDF-9. The self-sealing design means coupler halves only need to be closed hand tight. Yale provides an important operational note: hydraulic couplers must always be completely closed, since otherwise the circulation cannot be released.

Suitable Applications

Per Yale: standard coupler half on all Yale 700 bar hydraulic cylinders, hand pumps and equipment. CFY-1 is the standard variant; CFY-2/CFY-18/CFY-10-S serve specific custom fitting requirements.

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.

  • Self-Sealing Female Half: inner ball mechanism seals in un-coupled condition.
  • Hand-Tight Closure: no tools required to mate.
  • 700 bar Maximum Pressure: Yale standard.
