Tecwerk Pushbutton-Safety coupling DN 7.4, external thread aluminium thread G 1/4 inch 1

High-quality, robust and durable, operable with one-hand, quick-lock coupling in safe design with high flow rates. Decoupling takes place by pressing the pushbutton twice. The first press vents the coupling, but the plug remains secured in the coupling. With the second press, the plug is safely released. This consequently prevents notorious ‘whiplash accidents’ and virtually eliminates risk of injuring the operator. Conforms to ISO standard DIN EN ISO 4414
