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 made of cast iron, so they are brittle and can be quickly opened with the strike of a sledge hammer. They are also known as Pressure Class 125 fittings. Use in noncorrosive environments.

Inline tees are also known as branch tees.
