About Pipe and Fittings

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

Pipe, Tubing, Hose, and Fittings

Low-Pressure Iron and Steel Threaded Pipe Fittings

Use these fittings for low-pressure applications in noncorrosive environments.

Low-Pressure Galvanized Iron
and Steel Threaded Pipe Fittings

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

Low-Pressure Brass and
Bronze Threaded Pipe Fittings

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

Standard-Wall Brass Threaded
Pipe Nipples and Pipe

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

Standard-Wall Brass Threaded
Pipe Nipple and Pipe Assortments

Keep various lengths of brass pipe on hand for applications requiring good corrosion resistance.

Low-Pressure Brass and
Bronze Threaded Pipe Flanges

Also known as Pressure Class 150 flanges, these brass flanges are designed for low-pressure applications.

Low-Pressure Brass Threaded
Pipe Fittings with Sealant

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as Pressure Class 125 fittings, they are built for use in low-pressure applications.

Low-Pressure Plated Brass Threaded Pipe Fittings

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

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.

Extreme-Pressure Brass Threaded Pipe Fittings

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

Thick-Wall Brass Threaded Pipe Nipples and Pipe

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

Brass and Bronze Unthreaded Pipe Flanges

Bolt these flanges to another same-size flange with a gasket to create an access point within a pipe line. They are also known as Silbraze flanges.

Thick-Wall Plastic Pipe Fittings for Water

Connect these fittings to Schedule 80 pipe. With thicker, stronger walls than standard-wall fittings, they can handle heavy duty supply applications, such as water processing, wastewater treatment, and irrigation.

Yor-Lok Fittings for Copper Tubing

A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal.

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.

Tight-Seal Barbed Hose Fittings for Air and Water

Also known as ball-seat hose nipples, these fittings consist of a barbed shaft with a rounded end that sits inside a female threaded nut. When mated with a male threaded fitting, the rounded end presses tightly against the inside of the male threads for a better seal than a single-piece fitting. Once assembled, insert the barbed end into hose and secure with a clamp or a crimp-on hose ferrule.

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.

Threaded Gradual On/Off Valves for Cryogenic Liquid

Threaded Gradual On/Off
Valves for Cryogenic Liquid

Built to handle the extreme cold of liquid gases, these bronze valves are ideal for liquid carbon dioxide carbonation systems, liquid nitrogen coolant systems, and other cryogenic applications.
