Collection:DN 5 Air Coupling Plugs

View Tameson's wide range of DN 5 air coupling plugs. 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. 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.
