• Air Claw Couplings: 'EA', 'Minsup', 'UA', GK, Express

  • We provide quick-disconnect claw couplings mainly for air and water-transferred hoses. They are produced in basically hot-stamped brass alloy, carbon steel and stainless steel materials.
  • European air couplings are available in the range from DN10 to DN25, Minsup DN13 ~ DN25, Chicago couplings DN6 ~ DN25, GK DN6 ~ DN38 and Express fittings ¼" ~ 1¼".
  • The series are made according to multiple standards like DIN-3489, or tailered dimensions per specific demands for equipments. The interchangeability with those from high-profiled brands like 'Ludecke' and 'Karasto' is out of question.
  • Semi-Stock, Thousands of Pieces

  • Instead of producing on order
    We stock forging and casted billets which usually takes long
    Instant machining for prompt deliveries any time soon!
  • Unified Claw Distances

  • Claw couplings are universally compatible couplings, in that the mating size of the half piece is identical no matter sizes, materials or types like with hose tail, adapter or blind cap.

  • Note: In the table we state the claw distances per relevant norms or dominant standards in the market. Yet possibility still lies in there when one manufacturer can develop unique dimension, with cautions about interchangeability.
