Screw-on couplings suitable for general purpose applications. Connectable under residual pressure. High resistance to pressure and flow impulses. Interchangeable according to ISO 14541 standard for size: 1/4"; 3/8"; 1/2"; 3/4".
Working Pressure according to ISO 14541, that requires a safety factor 4:1 on minimun burst pressure. The couplings can perfectly work with a safety factor 3:1 and consequently with higher working pressure
