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 Brass and Bronze
Threaded Pipe and Pipe Fittings

Low-Pressure Brass Threaded
Pipe and Pipe Fittings with Sealant

The male threads have a thread sealant applied for extra protection against leaks.

Miniature Low-Pressure
Brass Threaded Pipe Fittings

Less than an inch in length, these miniature fittings work well in low-pressure pipe lines that are tight on space.

Low-Pressure Chrome-Plated Brass
Threaded Pipe and Pipe Fittings

The polished chrome plating not only provides a shiny appearance, but also improves corrosion resistance.

Medium-Pressure Brass and Bronze
Threaded Pipe and Pipe Fittings

Use in medium-pressure applications up to 400 psi.

High-Pressure Brass Threaded
Pipe and Pipe Fittings

Use in high-pressure applications up to 1,000 psi.

Extreme-Pressure Brass
Threaded Pipe and Pipe Fittings

Use in extreme-pressure applications up to 5,600 psi.

Brass and Bronze Unthreaded
Pipe and Pipe Fittings

Braze fittings to pipe for a permanent connection. Brazed connections are stronger than threaded connections and are less likely to leak.
