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.

Medium-Pressure Brass and
Bronze Threaded Pipe Fittings

Choose these fittings when you need better strength than our low-pressure brass and bronze pipe fittings.

Extreme-Pressure Brass Threaded Pipe Fittings

Extreme pressures are no problem for these heavy-duty brass fittings.

Precision Extreme-Pressure
Brass Threaded Pipe Fittings

Also known as instrumentation fittings, these have the most precise threads and the tightest tolerances of all the brass pipe fittings we offer.

Standard-Wall Brass Threaded
Pipe Nipples and Pipe

Typically used with low-pressure brass and bronze threaded pipe fittings.

High-Pressure Brass Threaded Pipe Fittings

These brass fittings have the strength to handle high-pressure applications.

Stainless Steel Threaded Pipe and Pipe Fittings

Precision Extreme-Pressure Stainless
Steel Threaded Pipe Fittings

These fittings are made to tighter tolerances than other stainless steel pipe fittings. They are also known as instrumentation fittings.

Extreme-Pressure Stainless
Steel Threaded Pipe Fittings

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

Low-Pressure Stainless Steel Threaded Pipe Fittings

Use these corrosion-resistant fittings in a low-pressure pipe line.

Standard-Wall Stainless Steel
Threaded Pipe Nipples and Pipe

Typically used with low-pressure stainless steel threaded pipe fittings.

Iron and Steel Threaded Pipe and Pipe Fittings

Compact Extreme-Pressure
Steel Threaded Pipe Fittings

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Standard-Wall Steel Threaded
Pipe Nipples and Pipe

Also known as Schedule 40, this steel pipe is designed for low-pressure applications.

Standard-Wall Galvanized Steel
Threaded Pipe Nipples and Pipe

Made of galvanized steel, this Schedule 40 pipe has fair corrosion resistance and is designed for low-pressure applications.

Thick-Wall Steel Threaded Pipe Nipples and Pipe

Typically used with medium-pressure iron and steel threaded pipe fittings. Also known as Schedule 80.

Aluminum Threaded Pipe and Pipe Fittings

Medium-Pressure Aluminum Threaded Pipe Fittings

Designed for medium-pressure applications, these fittings have better strength than our low-pressure aluminum pipe fittings.

Standard-Wall Aluminum
Threaded Pipe Nipples and Pipe

Typically used with low-pressure aluminum threaded pipe fittings.

Right-Angle Flow Rectangular Manifolds

Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers.
