Insert tubing into the push-to-connect fittings on these valves—no heat, solder, or flux required. They meet NSF/ANSI 51 for safe use with food and NSF/ANSI 61 for safe use with drinking water.

Full-port valves do not restrict flow.

Also known as flush-face couplings, the plugs and sockets have a flat face, which allows them to mate close against each other, reducing fluid loss when connecting and disconnecting the line. A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them when you need frequent access to a line. All of the International Standard ISO Minimal-Spill quick-disconnect plugs are compatible with any of the International Standard ISO Minimal-Spill quick-disconnect sockets of the same coupling size, regardless of the pipe size. Couplings are compatible with ISO 16028 Parker FEM, ISO 16028 Perfecting HT, and ISO 16028 Snap-Tite 74 couplings. Also known as double shut-off couplings, the plugs and sockets both have a shut-off valve that stops the flow when the coupling is separated. They are zinc-plated steel, which has excellent strength and durability and fair corrosion resistance.

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.

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.

Mount these valves onto compressed gas tanks. Also known as Schrader valves—which are typically used with compressed air—they have an internal spring that holds the valve shut when you depress the pin to add, remove, or check the pressure of compressed gas. Made of brass, these valves thread onto nuts more easily than valves made of harder metal. They also have good corrosion resistance. Valves have a thread cap to protect the stem from accidental gas release.

Valves for use with butane are commonly used on torches. They’re nickel plated for extra corrosion resistance.

Valves for use with nitrogen are often used in central heating systems.
