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 Stainless Steel
Threaded Pipe and Pipe Fittings

Use in low-pressure applications under 300 psi.

Extreme-Pressure Stainless
Steel Threaded Pipe Fittings

Use these fittings in extreme-pressure conditions up to 15,000 psi.

High-Pressure Stainless Steel
Threaded Pipe and Pipe Fittings

Use in high-pressure applications up to 6,000 psi.

Medium-Pressure Stainless
Steel Threaded Pipe Fittings

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

Stainless Steel Unthreaded Pipe and Pipe Fittings

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

Iron and Steel Pipe and Pipe Fittings

Iron and steel are more economical than stainless steel. They are compatible and can be used interchangeably.

Brass and Bronze Pipe and Pipe Fittings

Brass and bronze have good corrosion resistance. They are often used in drinking water and plumbing applications. Brass and bronze are compatible and can be used interchangeably.

Aluminum Pipe and Pipe Fittings

Aluminum has good corrosion resistance and is lightweight.

Plastic Pipe and Pipe Fittings

Plastic pipe and pipe fittings are lighter in weight than metal pipe and pipe fittings. They are typically for low- to medium-pressure applications up to 1,000 psi.
