Home / Products / Industrial hoses and fittings / Industrial fittings/ Compressed air couplings GK, express, Europian air standart
The European air (EA) air coupling is a high-load quick coupling manufactured in accordance with DIN 3489.
Assembly
- Worm drive clamps
- Two-bolt saddle clamps
Material
Coupling
Galvanized steel, stainless steel AISI 316, 14401
Seal
NBR
Temperature
-30 ° C / -22 ° F до 120 ° C / 248 ° F
The hose, coupling, assembly method and seal must be selected according to the desired application and temperature range.
Threads
External thread: EN 10226-1 / DIN 2999, BSPT (does not comply with DIN 3489)
Internal thread: EN ISO 228-1, BSP
Application
For air and water
N.B.: European air couplings should never be used for steam
Working pressure
10 bar / 145 psi
Operation
The distance between the teeth is standardized to 42 mm. The couplings are pressed and turned to seal. Due to the side-mounted seal and its angular shape, an instantaneous force is set, which prevents pressure loss due to vibrations.
The head of the European air coupling is identical and interchangeable with other versions of the European air coupling
Features
- Claw distance: 42mm
- EA couplings feature a specially designed NBR seal, whose lateral and angular shape offers excellent compression properties. Pressure is applied as soon as the coupling is connected.
- Serrated hose end for perfect resistance when assembled with worm drive clamps or tooth clamps
