EA DIN 3489 Fittings
EA o European Air: Symmetric coupling for air and water applications, never be used for steam applications. The couplings are pushed together and rotated to form a seal. Due to the lateral and angular shape of the seal an instant force is set, which prevent pressure loss due to vibration. These look similar to Express and Geka couplings, but EA couplings have a 42 mm distance between the claws. European air couplings are heavy-duty claw couplings manufactured in compliance with DIN 3489, in carbon steel with BSP thread, hose shank or blind cap.
