Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings. They’re also known as flush-face and double shut-off couplings. A complete coupling consists of a plug and socket (both sold separately). They connect and disconnect quickly, so use them if you need to access a line frequently. Made of 316 stainless steel, they have excellent corrosion resistance and withstand a variety of chemicals.
Plugs are also known as nipples.
Sockets are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects. These sockets have an internal fluoroelastomer gasket that resists a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings are given for static (constant) pressure conditions.
Warning: Never attempt to connect or disconnect couplings when operating at maximum pressure. Stop the flow before you disconnect the line.
