Open-Flow Quick-Disconnect Hose Coupling for Air and Water
Manufacturer part: 6543K44
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.Plugs are also known as nipples.303 stainless steel plugs and sockets have very good corrosion resistance. They’re the best choice for high-humidity environments.Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.Warning: There is no valve in these couplings. Stop the air and water flow before you disconnect the line.
