Collection:DN 5 Air Coupling Sockets With Union Nut

View Tameson's wide range of DN 5 air coupling sockets with union nut. The DN 5 profile is a popular standard size for air couplings. They are amongst others compatible with Rectus 21 and 90, Camozzi, EWO and KANI. Mount a hose with the use of the union nut. Slide the nut over the hose, push the hose over the hose pillar and then fix the hose by tightening the nut. Make sure that the inner and outer diameter of your hose match with the specifications of the union nut connection. A pneumatic coupling is used to quickly connect air tools to a compressed air line. The coupling requires two parts: the socket (female) and the plug or nipple (male part). When disconnected, the coupling automatically seals off to maintain the line pressure. They are often referred to as compressed air couplings, compressor couplings, pneumatic fittings, air hose couplings, etc.
