About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Metal Pipe and Pipe Fittings

Standard-Wall Stainless Steel
Threaded Pipe Nipples and Pipe

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

Standard-Wall Stainless Steel
Unthreaded Pipe Nipples and Pipe

Typically used with standard-wall and low-pressure stainless steel unthreaded pipe fittings.

Thin-Wall Stainless Steel
Unthreaded Pipe Nipples and Pipe

Typically used with thin-wall stainless steel unthreaded pipe fittings.

Thick-Wall Stainless Steel Unthreaded Pipe

Typically used with thick-wall and high-pressure stainless steel unthreaded pipe fittings.

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.

Standard-Wall Steel Unthreaded
Pipe Nipples and Pipe

Typically used with standard-wall and low-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 40.

Standard-Wall Aluminum
Threaded Pipe Nipples and Pipe

Typically used with low-pressure aluminum threaded pipe fittings.

Standard-Wall Aluminum
Unthreaded Pipe Nipples and Pipe

Typically used with standard-wall aluminum unthreaded pipe fittings.

Plastic Pipe and Pipe Fittings for Water

Thick-Wall Plastic Pipe for Water

Connect to thick-wall plastic pipe fittings for use in heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Pipe can handle pressures up to 900 psi.

Clear-View Thick-Wall Plastic Pipe for Water

See what’s flowing through your line with this clear pipe. Since it’s Schedule 80, this pipe has thicker, stronger walls than standard-wall pipe, so you can use it for heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation.

Standard-Wall Plastic Pipe for Water

Connect this pipe to standard-wall plastic pipe fittings for a variety of residential and commercial low-pressure plumbing and water supply applications.

Clear-View Standard-Wall Plastic Pipe for Water

See inside your line with this clear pipe, which works in a variety of residential and commercial low-pressure plumbing and water supply applications.

CPVC Pipe for Hot Water

Connect to CPVC pipe fittings for use in high-temperature plumbing and water supply applications up to 170° or 200° F.

Hose Fittings

Metal Barbed Hose Fittings for Air and Water

Metal hose fittings have better durability than plastic barbed hose fittings.

Easy-Fit Barbed Hose Fittings for Air and Water

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into hose and secure with a clamp.

Metal Cam-and-Groove Hose Couplings for Water

Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.

Easy-Fit Barbed Hose Fittings for Chemicals

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into hose and secure with a clamp.

Metal Cam-and-Groove Hose
Couplings for Chemicals and Petroleum

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Vacuum Fittings for Steel Tubing

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.
