Coupling for compressed air : Express couplings & Air King couplings
Symmetrical rapid-lock quarter-turn couplings, comprising different rear parts depending on where they are intended to be installed.
Fluted Express coupling, female threaded Express, male threaded, swivel connection, Hose connection with safety collar, rubber gasket, clamping jaw, safety pin and female jonction
- European-type.
- American-type.

Warning concerning couplings intended for gaseous fluids
We would like to insist on the need to make a perfectly suitable choice of couplings and locking collars/rings on the compressed air pipe concerned.
In fact, as the fluid is compressed by definition, the damage if the hose breaks is much greater than that caused by a fault on a hose transporting an incompressible fluid.
You can compare the breakage of a hose under pressure to compressed gas during an explosion.
Express couplings sizes :

Key :
1 : Triggering notch
2 : Catch
NOTE 1: The max. 25 mm diameter delimits a minimum bearing crown of the flange joint.
NOTE 2: The shapes and dimensions not marked are left to the interpretation of the manufacturer.

Express couplings : European-type
This coupling has a machined socket with non-aggressive locking for pipe tubes, a fastening neck for fitting a handle collar as well as a catch on this neck to prevent the collar from being turned.
There is no need to use a wrench to connect the pipework.
The distance between the handles is 41mm, sealing is done by a seal, which may have a large hole (water application) or a small hole (air application).
Heavy series - French norm
Conditions of use : Water, Compressed air
Express design based on NF E29-573 standard (claw distance 41 mm).
Works with all fittings based on the same standard.
