Tanker couplings, also known as TW couplings, are standardized in accordance with EN 14420-6 (formerly DIN 28450) and are interchangeable throughout Europe. The couplings consist of a V-part (male part) and an M-part (female part), which are pressed against each other by twisting the clamping ring lever and thus seal against the seal in the crown piece of the female part. The clamping ring lever is folded back after twisting and thus locks the connection between the two coupling parts. The couplings have no valves and a large free flow area with a nominal width of 50, 80 or 100 mm. caution: Risk of injury: Before uncoupling, ensure that the coupling is depressurized!
