How to Identify and Measure Fittings

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

Temperature Range: -210° to 270° F
Tubing: Use with firm or soft (Durometer 45A-90A) polyurethane rubber or PVC plastic

Monitor flow with these clear fittings. They have a single barb that creates a smooth clamping surface for extra-tight connections that minimize leaks. Fittings are polycarbonate for excellent impact resistance.

Plastic Quick-Turn Tube Couplings for Air and Water

For Use With: Polycarbonate Plastic: Air
Nylon Plastic: Air, Water
Polypropylene Plastic: Water
Temperature Range: Nylon Plastic, Polycarbonate Plastic: -20° to 200° F
Polypropylene Plastic: 35° to 150° F
Tubing: Use with soft (Durometer 40A-65A) PVC plastic or silicone rubber

Made of plastic, these couplings are lighter in weight than metal quick-turn couplings. Also known as luer lock couplings, they consist of a plug and socket (sold separately) that connect with a half turn. They have a compact body for easy installation in tight spaces. Plugs and sockets are open-flow style, so there is no shut-off valve to stop the flow when the coupling is separated. They have a universal connection, so the plugs will connect to any of the sockets, regardless of the pipe or tube size.

Polycarbonate plugs and sockets are clear so you can monitor your line. Note: For a complete coupling, order a plug and a socket.

Straight Plugs, Barbed Tube

Barbed plugs and sockets insert into tubing and secure with a clamp.

Plastic On/Off Valves with Barbed Fittings

Barbs grip onto tubing, providing a secure hold.

T-handles resist accidental movement when snagged or bumped.

Standard-port valves slightly restrict flow.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

On/Off Valves with Quick-Turn Fittings

Also known as luer-lock couplings, quick-turn fittings consist of a plug and a socket that connect with a half turn, so you can easily connect and disconnect your line.

Polycarbonate valves are lightweight and more economical than nickel-plated brass valves, but they are not as durable. These valves have a T-handle that resists accidental movement when snagged or bumped.

Food Industry Solenoid On/Off Valves with Push-to-Connect Fittings

For Use With: Food, Beverage
Seal Material: EPR Rubber
Specifications Met: CSA Certified, NSF/ANSI 169

Insert tubing into the fittings on these valves—no heat, solder, or flux required. Valves meet NSF/ANSI 169 for use with food equipment. They operate on electricity to automatically start and stop flow.

All are normally closed unless actuated. Valves don’t require a minimum pressure drop between the inlet and outlet for operation. The actuator is directly mounted to the valve body to minimize movement and reduce wear.

Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
