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.

High-Pressure Iron and Steel Threaded Pipe Fittings

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

Tee outlets allow you to create a threaded outlet anywhere along a pipe. They are also known as branch connectors and are comparable to Thredolet. To install, drill a hole in your pipe to match the fitting’s pipe size and weld in place.

Phosphate-coated and zinc-phosphate-coated fittings offer some corrosion resistance, but aren't intended for corrosive environments.

High-Pressure Socket-Connect Steel Unthreaded Pipe Fittings

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings have heavy duty construction that stands up to high-pressure applications. They are for use in noncorrosive environments.

Tee outlets allow you to create a tap anywhere along a pipe. They are also known as branch connectors and are comparable to Sockolet. To install, drill a hole in your pipe to match the fitting’s pipe size and weld in place.

Thick-Wall Butt-Weld Steel Unthreaded Pipe Fittings

With thick walls, these fittings are the strongest steel butt-weld fittings we offer. Weld them flush against pipe to provide a smooth connection for maximum flow. Fittings have beveled ends that create a trough for a leak-resistant, permanent weld. Use in noncorrosive environments.

Tee outlets allow you to create a tap anywhere along a pipe. They are also known as branch connectors and are comparable to Weldolet. To install, drill a hole in your pipe to match the fitting’s pipe size and weld in place.

High-Pressure Socket-Connect Stainless Steel Unthreaded Pipe Fittings

Forged for excellent strength, these heavy duty socket-connect fittings stand up to high-pressure applications. They are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection.

304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

Standard-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 40 plastic pipe–they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

Fittings for drinking water meet NSF/ANSI Standard 61.

Attach socket-connect ends to unthreaded pipe or another socket-connect fitting with a PVC primer and cement (also known as solvent weld).

To prevent leaks in threaded connections, apply a sealant to the male threads. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. Fittings that meet ASTM D1784, ASTM D1785, and ASTM D4066 adhere to specifications and testing requirements for material quality.

Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Remote-Reading Socket-Connect Flowmeter/Totalizers for Water

With a display that can be placed up to 25 feet from the sensor, these flowmeter/totalizers are often used in hard-to-access areas. For a complete unit, order a display, a sensor, and a tee fitting.

Tee fitting has two unthreaded female socket end connections; connect with PVC cement and primer.
