Typically used with thin-wall aluminum unthreaded pipe fittings.

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.

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

Typically used with high-pressure aluminum threaded pipe fittings.

Their small size makes these miniature fittings a good choice for cramped, confined spaces.

Twist these fittings onto aluminum pipe for quick, sealed connections—no threading, soldering, or welding necessary. Use them to build a compressed air system in half the time it would take to build a copper or steel system.

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.

With better strength than our low-pressure steel flanges, these are for use in medium-pressure applications.

Use these unions to connect different metals in a piping or plumbing system. They have a gasket with a plastic sleeve that inhibits destructive corrosion.

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.

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

FM-approved for fire protection applications, these flanges are cast iron, so they're brittle and can be quickly opened by hitting them with a sledge hammer.

Typically used with thick-wall and high-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 80.

With thicker, stronger walls than our standard-wall butt-weld pipe fittings, these fittings stand up to your high strength applications.

Typically used with extreme-pressure iron and steel unthreaded pipe fittings. Pipe is also known as Schedule XXH .

Also known as Pressure Class 6000 fittings, these heavy duty forged fittings are the strongest steel fittings we offer.

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.

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

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