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.

Thick-Wall Butt-Weld Stainless Steel Unthreaded Pipe Fittings

With a thicker wall than our standard-wall butt-weld pipe fittings, these offer high strength while providing a smooth connection for maximum flow. They have beveled ends that, when flush to pipe, create a trough for a leak-resistant, permanent weld.

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