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.

More

Pipe, Tubing, Hose, and Fittings

Iron and Steel Pipe and Pipe Fittings

testString

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

Stainless Steel Pipe and Pipe Fittings

testString

Stainless steel has very good to excellent corrosion resistance.

Aluminum Pipe and Pipe Fittings

testString

Aluminum has good corrosion resistance and is lightweight.

Brass and Bronze Pipe and Pipe Fittings

testString

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.

Titanium Threaded Pipe Fittings

Titanium Threaded Pipe Fittings

Titanium has similar strength to steel, but is approximately 40% lighter. It has better corrosion resistance than most stainless steel alloys and can handle corrosive substances, such as salt water and acids.

Copper-Nickel Pipe and Pipe Fittings

testString

Copper-nickel has excellent resistance to stress cracking and has better corrosion resistance than most stainless steel alloys. It can stand up to corrosive environments, such as salt water applications.

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.

Clamp-On Connectors

Clamp-On Connectors

Use these to connect plastic or metal pipe of the same or different materials. Tighten the bands to form a strong seal.
