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 Plated Brass Threaded Pipe Fittings

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

Chrome-plated brass fittings are shinier and withstand corrosion better than nickel-plated brass fittings.

Union connectors separate into three pieces so you can access your line without unthreading pipe connections.

Locknuts thread onto the male end of a fitting to provide extra holding power so the fitting won’t loosen from vibration.

Female x male 90° elbow adapters are also known as street elbows.

Inline tees are also known as branch tees.

Standard-Wall Chrome-Plated Brass Threaded Pipe Nipples and Pipe

The polished chrome plating gives this brass pipe a bright, shiny appearance and provides extra corrosion resistance. Also known as Schedule 40 pipe, it is commonly used in low-pressure applications. Pipe is seamless so it has a smooth interior for unrestricted flow.

Fully threaded pipe is also known as a close nipple; it is threaded on each end to the center.
