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 Iron and Steel Threaded Pipe Fittings

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

Right-angle tees are also known as run tees. Inline tees are also known as branch tees. Dual tees reduce on all three ends.

FM-Approved Low-Pressure
Cast Iron Threaded Pipe Fittings

Suitable for use in fire-protection applications, these pipe fittings are brittle and can be quickly opened with the strike of a sledge hammer. They are also known as Class 125 fittings. Use in noncorrosive environments.

Inline tees are also known as branch tees.

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.
