Couplings are FDA compliant, so they’re suitable for food and beverage applications and won’t impart tastes or odors to the product. A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them if you need frequent access to a line. All of the International Standard ISO B quick-disconnect plugs are compatible with any of the International Standard ISO B quick-disconnect sockets of the same coupling size, regardless of the pipe size. They are compatible with ISO 7241-1 Series B and Parker 60 couplings. Also known as double shut-off couplings, the plug and the socket both have a shut-off valve that stops the flow when the coupling is separated, so product won’t leak from the line. Plugs and sockets are acetal for excellent corrosion and moisture resistance, so they won’t absorb water and lose strength, even in high-humidity environments.

Plugs are also known as nipples.

Sockets are sleeve-lock style. To connect, slide back the sleeve on the socket, insert the plug, and release the sleeve. To disconnect, slide back the sleeve and pull out the plug.

Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings reflect static (constant) pressure conditions.
