To prevent leaks in low-pressure lines, the male threads on these fittings have an acrylic sealant already applied for extra protection.

The male threads on these fittings have a sealant applied for extra leak protection.

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

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

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

Bolt two flanges of the same size together with a gasket to create an access point in a pipe line.

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

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.

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.

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.

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

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

Press these fittings onto stainless steel pipe using a crimping tool for a permanent, leak-tight connection that's faster than threading or welding and doesn't require heat.

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.

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

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.

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

Use these heavy-duty brass fittings for high-pressure drinking water applications.

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

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

When you're unsure of the exact thread type you need, these fittings have universal threads that are compatible with the most common ones (NPT, NPTF, BSPP, BSPT).

Also known as Pressure Class 3000 fittings, these have the highest pressure rating of all the aluminum pipe fittings we offer.

Use these unthreaded flanges in low-pressure applications. Also known as Pressure Class 125 flanges.

Connect these fittings to thick-wall plastic pipe—they have thicker, stronger walls than standard-wall fittings, so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They can withstand pressures up to 900 psi.

Use for pressures up to 200 psi. Also known as insert fittings, these slide into semi-flexible plastic pipe and secure with a clamp.

Bolt two same-size flanges together with a gasket to create an access point within a line. They are also known as Pressure Class 150 flanges. Use in high-temperature plumbing and water supply applications up to 200° F.

Use these polypropylene flanges in outdoor environments—they resist the damaging effects of ultraviolet light. They have the chemical resistance to stand up to acids, solvents, and other harsh substances. Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges are also known as Pressure Class 150 flanges.

Not only do these PFA fittings have the chemical resistance to handle acid and salt water, they also have better crack resistance than other plastic pipe fittings for chemicals. They are commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications.

Use these plastic fittings to connect gasoline fuel lines to machines and equipment. They have excellent corrosion resistance as well as high strength and impact resistance.

Made of PVDF, also known as Kynar, these fittings stand up to the harsh chemicals used to clean food processing lines. Unlike other plastic fittings, such as nylon and acetal fittings, they’ll resist degrading when exposed to strong alkali and highly acidic solutions.

These flexible plastic caps are tapered to fit a variety of unthreaded and threaded objects.

Push these caps onto pipe and fittings, then tear their tab to break the seal for easy removal.

Stick these caps on the raised surfaces of flanges or other flat surfaces for extra protection during transport and storage.

Protect SAE hydraulic flanges during shipping, storing, and finishing applications.

Protect internally threaded NPT connections from contaminants during fabrication and storage.

Safeguard internally threaded BSPT connections from contaminants during fabrication and storage.

Pull the two built-in rings to quickly remove these plugs. All are tapered to fit a range of hole diameters.
