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.

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.
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.
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.
