Project Description


Air hose coupling

Double Well provides quick-disconnect claw couplings mainly for air and water-transferred hoses. The couplings are pushed together and rotated to form a seal. Due to the lateral and angular shape of the seal and instant force is set, which prevent pressure loss due to vibration.

The series are made according to multiple standards like DIN-3489, or tailored dimensions per specific demands for equipments. The interchangeability with those from high-profiled brands like ‘Ludecke’ and ‘Karasto’ is out of question.


Double Well provides professional solutions concerning industrial hoses and couplings as well as industries pipe fittings and valves for industry, located in north of China. Our main products include hose couplings ( Camlock coupling,Air hose coupling, Bauer coupling), fire fighting couplings ( Stroz coupling, Guillenmin couplings, John Morris couplings, Machino coupling, Barcelona coupling Forestcouplings, fire nozzles), pipe fittings(stainless steel pipe fittings, malleableiron pipe fittings, flanges, sanitary pipe fittings) and valves ( ball valve,gate valve, sanitary butterfly valve ) and so on.

Adavantage of Air hose coupling:

Good abrasion resistant, light weight, economical cost;
Save time compared with flanged or threaded fittings;
No tools needed and make the job easy;
Safety sealing for fluids, powders and pellets,Light weight and durable;
Could keep the transfers safe without any damage or any risks.
