A complete coupling consists of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are also known as industrial interchange couplings. All Industrial plugs are compatible with any of the Industrial sockets of the same coupling size, regardless of the pipe size or barbed hose ID.

How It Works
  • To disconnect, begin by holding the hose on the nipple side with three of your fingers, leaving your thumb and index finger free.
  • Grab the sleeve with your thumb and index finger and begin to pull the sleeve towards the palm of your hand.
  • After pulling the sleeve, the nipple will move out of the coupler slightly. Continue to hold the hose and coupler sleeve until all air is fully exhausted.
  • After the line is fully exhausted, you are able to safely separate the nipple from the coupler.
