Collection:Color Coded Air Couplings (Non-Interchangeable)

View Tameson's wide range of color coded air couplings (non-interchangeable). These air couplings are available in different colors with each a distinctive connection shape (octagon, triangle, circle). Plug and sockets of the same color can be combined. Two different colors cannot be combined. This prevents the risk of accidentally connecting to a wrong medium or pressure line. Please note that a color coded plug or socket is still compatible to the same size standard non-color coded socket or plug. 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.
