Claw couplings
Claw couplings – general information
Claw couplings are broadly used for air and water in industry and construction. Both halves of the coupling are exactly the same – no distinction between a coupler and an adapter. They have two lugs (claws) each, which engage in the corresponding notches of the opposite half. That is why they can be connected so easily – just by pushing two part together and turning. However, only the elements of the same type, with the same claw distance can be interconnected. The claw couplings are divided into the following types:
- claw distance 42 mm – typical European compressed air couplings;
- claw distance 40 mm – typical water couplings, also called GEKA couplings;
- claw distance 41 mm – American compressed air couplings (US type);
The claw couplings are made of zinc-plated cast iron, brass, stainless steel and always come with an oil resistant NBR rubber seal (Viton for stainless steel).
Our product range includes:
- couplings with a hose tail (from 10 to 38 mm);
- couplings with male or female thread;
- blank caps;
- Y fittings fitted with couplings.
The claw couplings are assembled to hoses with malleable iron hose clamps or other clamps.
The claw couplings cover such applications as: compressed air transfer, connecting pneumatic tools and pneumatic systems, water systems in the industry, at construction sites, agriculture and horticulture.

FAQ – Claw couplings:
The claw distance does matter, as there are different types of claw couplings. The most popular claw distance is 42mm, 41mm and 40mm (so-called GEKA couplings). Never join couplings with different claw distance.
Yes, it is. Before choosing the material, it is necessary to determine what medium these couplings will be used for. Standard coupling materials include zinc-plated cast iron, brass and stainless steel. In addition, the sealing material must be chosen: NBR or Viton.
Claw couplings (with the same claw distance) are connected by pressing two couplings against each other and rotating. The claws engage in the gaps in the claws of the opposite half.
