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.

On/Off Valves with Push-to-Connect Fittings

Insert tubing into the fittings on these valves—no heat, solder, or flux required. They’re for use with water, oil, air, and inert gas.

On/Off Valves with Yor-Lok Fittings

For extra gripping power and a strong seal, the Yor-Lok fittings on these valves have two sleeves that bite into tubing as you tighten the nut. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings. These valves are for use with water, oil, air, and inert gas.

On/Off Valves with Push-to-Connect
Fittings for Food and Beverage

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.

Plastic On/Off Valves with Push-to-Connect
Fittings for Drinking Water

For a lightweight and economical alternative to metal, these valves are made of plastic. Insert tubing into the fittings—no heat, solder, or flux required. All meet NSF/ANSI 61 for use in drinking water systems.

Check Valves with Push-to-Connect Fittings

Insert tubing into the fitting—no heat, solder, or flux required.

Check Valves with Yor-Lok Fittings

Two sleeves give the fittings extra gripping power. They bite into tubing as you tighten the nut to form a strong seal. All are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Check Valves with Push-to-Connect
Fittings for Drinking Water

Valves have a plastic body.

Flow-Control Mufflers

Adjust the flow by turning the screw. Use these mufflers with air-powered tools and cylinders to reduce noise and filter exhaust fumes.

Pipe, Tubing, Hose, and Fittings

International Standard ISO Minimal-Spill
Quick-Disconnect Hose Couplings for Hydraulic Fluid

Use these couplings at pressures up to 7,200 psi. Also known as flush-face couplings, the plugs and sockets have a flat face, which allows them to mate close together, reducing fluid loss when connecting and disconnecting the line. They are compatible with International Standard ISO Minimal-Spill-shape plugs and sockets.

Air Fill Valves

Also known as Schrader valves, these valves rapidly fill or empty compressed air tanks or pneumatic tires.

Compressed Gas Fill Valves

Mount these valves onto compressed gas tanks.

Push-to-Connect Tube Fittings with Shut-Off for Air

A built-in shut-off valve stops airflow when the fittings are disconnected from tubing.

Plastic Quick-Disconnect Tube
Couplings for Air and Water

Lighter in weight than metal quick-disconnect couplings, these couplings are plastic.
