Product information "DN 7.4 safety coupling, black, push button, rotatable, QN: 1,800 Nl/min, MOP 232 psi, G¼ male, L: 70.5 mm, AF 21"
DN 7.4 safety coupling with push button, according to ISO 4414, DIN EN 983, is rotatable, and silicone-free. The push button release prevents the so called whip effect during decoupling. The used materials and wear out parts are completely made of zinc-plated steel, the housing is made of aluminum. The corrosion-resistant, high-grade couplings are characterized by their robustness and long life cycle. Threads and hose connections are rotatable under pressure. Regarding firmly attached couplings the swivel joint allows the best ergonomic position for the push button. 360° rotation axis. High ease of use due to the integrated recessed grip. The coupling is available with different types of connectors. Basic version: housing color is green with an ewo logo. REACH and RoHS conform. Handeling: step 1: activate the push button once to vent the coupling, meanwhile the plug is still secured within the sleeve. Step 2: By pressing the button a second time the plug is unlocked and can be removed safely.
