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.

Low-Pressure Aluminum Threaded Pipe Fittings

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

Low-Pressure Stainless Steel Threaded Pipe Fittings

Use these corrosion-resistant fittings in a low-pressure pipe line.

Low-Pressure Iron and Steel Threaded Pipe Fittings

Use these fittings for low-pressure applications in noncorrosive environments.

Grooved-End Iron Pipe Fittings

The grooved ends on these iron fittings connect to pipe with a clamp to easily install piping systems.

Clamps for Easy-Access UV-Resistant
Polypropylene Pipe Fittings for Chemicals

Use these clamps to connect easy-access UV-resistant polypropylene pipe fittings to pipe. The clamp-together design allows you to access your line for routine maintenance.

Clamps for Easy-Access CPVC
Pipe Fittings for Chemicals

Use these clamps to connect easy-access CPVC pipe fittings and pipe.

Push-to-Connect Fittings for Plastic and Rubber Tubing—Air and Water

Stainless Steel Push-to-Connect
Tube Fittings for Air and Water

A 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube fittings.

Brass Push-to-Connect Tube Fittings for Air

Made of brass, these fittings have good corrosion resistance.

Push-to-Connect Tube Fittings for Air

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.

Moisture-Resistant Push-to-Connect
Tube Fittings for Air and Water

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications.

Tube Fittings for Metal Tubing

37° Flared Fittings for Stainless Steel Tubing

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°.

37° Flared Fittings with Thread
Sealant for Stainless Steel Tubing

The male pipe threads on these fittings have a sealant applied for extra protection against leaks.

Through-Wall Fittings for High-Vacuum Chambers

Transfer liquids and gasses into high-vacuum chambers with these assembled fittings, also known as feedthroughs.

Yor-Lok Fittings for Stainless Steel Tubing

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

37° Flared Fittings for Steel Tubing

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on steel tubing that is flared to 37°.

Compressed Gas Hose Fittings

Nuts for High-Pressure Nipples for Compressed Gas

These nuts attach to high-pressure nipples for compressed gas so you can connect your tank to the inlet of a pressure regulator.

High-Pressure Nipples for Compressed Gas

Commonly used in high-pressure welding applications, these nipples connect your tank to the inlet of a pressure regulator. One side has a threaded pipe end and the other side has a rounded end that sits inside a threaded nut to make a threaded connection.

High-Pressure Threaded
Fittings for Compressed Gas

Designed to handle high-pressure welding applications, these CGA fittings are commonly used to connect pressure regulators to compressed gas tanks or cylinders.

Threaded Hose-to-Propane-Tank
Adapters for Compressed Gas

These CGA adapters have a male threaded end that connects to a propane tank and a male threaded end that connects to welding hose.

Nuts for Barbed Hose Fittings for Compressed Gas

Also known as CGA nuts, these are designed for low-pressure welding applications downstream of your pressure regulator. Attach them to barbed hose fittings for compressed gas to make a threaded connection to torches or pressure regulators.

High-Temperature Metallic Pipe Gaskets

Long-Life High-Temperature Metallic Pipe Gaskets

A space between the outer ring and the sealing element prevents the element from being squeezed inward and contaminating the process line.

High-Temperature Metallic Pipe Gaskets

Also known as spiral-wound gaskets, these have a carbon steel outer ring and a 304 stainless steel inner sealing element with a graphite-based filler.

Easy-Install High-Temperature
Metallic Pipe Gaskets

Instead of bolt holes, these gaskets have tines that easily fit around flange bolts to ensure they’re properly aligned with pipe openings. The tine design also means you won’t have to retorque the flange for alignment, saving time.

High-Temperature Steam-Resistant
Metallic Pipe Gaskets

Made of 110 copper, these gaskets handle steam applications up to 600° F. They are electrically conductive and resist water, Freon, and fuel oil.

High-Temperature Chemical-Resistant
Metallic Pipe Gaskets

These gaskets have a carbon steel outer ring and a 304 stainless steel inside sealing element with a PTFE filler that’s virtually chemically inert. They're also known as spiral-wound gaskets.

Connectors for Lift Truck Propane Tanks

Use a valve, valve connector, and hose connector to create a complete connection between a propane tank and a lift truck's fuel hose.
