Save time installing sleeves and nuts—these sets come oriented in the correct direction and order on a dispenser.

Use these nuts with compression sleeves and fittings to create a strong seal on stainless steel tubing.

When used with high-pressure compression fittings and nuts, these sleeves bite into stainless steel tubing to form a strong seal.

Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps.

This hose meets CGA (Compressed Gas Association) standards for use with oxygen and acetylene gas.

Change the fuel source for your propane torch from a fuel cylinder to a propane tank. This hose is often used for extended-use applications, or when a propane tank can’t be moved.

These CGA adapters allow you to connect a hose to a propane torch.

These CGA adapters have a male threaded end that connects to a propane tank and a male threaded end that connects to welding hose.

Commonly used in high-pressure welding applications, these nipples connect your tank to the inlet of a pressure regulator. One side has a threaded pipe end and the other side has a rounded end that sits inside a threaded nut to make a threaded connection.

Use these couplings when you need frequent access to a gas line. A complete coupling consists of a plug and a socket that connect and disconnect quickly.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

Also known as Schedule 10 fittings, these are thin, lightweight, and corrosion resistant.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

Use these heavy duty forged flanges for high-pressure applications.

The strongest socket-connect fittings we offer, these heavy duty forged fittings are also known as Pressure Class 6000.

Keep a variety of lengths of pipe and pipe nipples on hand for areas where corrosion is a concern.

Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition.

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

Typically used with medium- to high-pressure stainless steel threaded pipe fittings.

Also known as ANSI flanges.

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

Assortments contain threaded pipe in various lengths.

Pipe has clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end. When you use a wrench to turn, connections on both ends tighten at the same time.

Use these Pressure Class 150 pipe flanges in low-pressure lines where temperatures drop down to -40° F.

The threads on these fittings have clockwise (right-hand) threads on one end and counterclockwise (left-hand) threads on the other end.

Suitable for use in fire-protection applications, these pipe fittings are made of cast iron, so they are brittle and can be quickly opened with the strike of a sledge hammer.

The acrylic sealant on this pipe offers extra protection against leaks. Also known as schedule 40 pipe, this pipe is designed for use in low-pressure environments.

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

One end of these fittings has clockwise (right-hand) threads and the other has counterclockwise (left-hand) threads. Their galvanized finish gives them fair corrosion resistance.

A galvanized finish gives these fittings fair corrosion resistance. They have the strength to handle medium-pressure applications.

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

For use in noncorrosive environments, these fittings have better strength than our low-pressure iron and steel pipe fittings.

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

The heavy duty caps and plugs in these assortments come in various sizes and stand up to high-pressure flow applications. Made of steel, they’re for use in noncorrosive environments.

A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Pressure Class 3000 fittings.

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat.

Even in temperatures as low as -46°, these A350 LF2 steel flanges won’t become brittle, so they absorb impact better than other low-pressure steel flanges.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

Forged for extra strength, these heavy duty unthreaded flanges can withstand high-pressure applications.

For excellent strength in extreme-pressure applications, choose these heavy duty Pressure Class 1500 flanges.

The plating on these brass fittings creates a shiny finish and provides extra protection in corrosive environments. Fittings have the strength to handle high-pressure applications.

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

Not only do these brass fittings have the strength to handle high-pressure applications, the male threads have a sealant applied for extra protection against leaks.

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

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

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

Typically used with medium-pressure brass and bronze 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.

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.

Also known as Pressure Class 200 fittings.

These fittings have excellent resistance to stress cracking and have better corrosion resistance than most stainless steel alloys.
