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.

DIN Rail Caps

Guard the edges of DIN rail from damage and create a finished look.

Threaded Round Plugs for BSPT Pipe

Safeguard internally threaded BSPT connections from contaminants during fabrication and storage.

Pipe, Tubing, Hose, and Fittings

Plastic Cam-and-Groove Hose Couplings for Water

Made of polypropylene, these cam-and-groove couplings are lighter in weight than metal cam-and-groove hose couplings.

Protective Plastic Plugs for
Cam-and-Groove Hose Sockets for Water

Insert these caps into a cam-and-groove socket to protect the end of the coupling from damage. The attached handle allows you to easily maneuver hose.

Cam-and-Groove Hose Couplings
for Food and Beverage

Couplings are made of FDA listed materials, so they’re suitable for food and beverage applications and won’t impart tastes or odors to the product. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Easy-Access UV-Resistant Polypropylene
Pipe Fittings for Chemicals

Also known as manifold flange fittings, these have a clamp-together design that lets you access your line for routine maintenance. Fittings resist acids, solvents, and other harsh chemicals. They won’t deteriorate when exposed to the damaging effects of ultraviolet light, so they’re suitable for outdoor use.

UV-Resistant Polypropylene Pipe Fittings for Chemicals

Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand acids, solvents, and other harsh substances.

UV-Resistant Polypropylene Pipe Flanges for Chemicals

Use these polypropylene flanges in outdoor environments—they resist the damaging effects of ultraviolet light. They have the chemical resistance to stand up to acids, solvents, and other harsh substances. Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges are also known as Pressure Class 150 flanges.

Push-to-Connect Fittings for Plastic Tubing—High-Purity

Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 140 psi.

Push-to-Connect Fittings for Plastic
Tubing—Food and Beverage

Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 150 psi.

Plastic Quick-Turn Tube Couplings for Air and Water

Made of plastic, these couplings are lighter in weight than metal quick-turn couplings.
