Description
Couplings allow for maximum flow because there’s no shut-off valve in the plug or the socket. 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 Open-Flow plugs are compatible with any of the Open-Flow sockets of the same coupling size, regardless of the pipe size. They are compatible with Hansen ST, Parker ST, and Perfecting E couplings.
