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.

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.

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.

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

Use these fittings in extreme-pressure conditions up to 15,000 psi.

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.

Plated with nickel, these brass fittings resist rust better than steel and unfinished brass fittings. Select them when you need more strength in corrosive environments to handle higher pressures than our low-pressure fittings.

Also known as instrumentation fittings, these have the most precise threads and the tightest tolerances of all the brass pipe fittings we offer.

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

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.

Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand acids, solvents, and other harsh substances.

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.

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

The hollow construction allows these plugs to compress for a snug fit in threaded and unthreaded holes of varying diameters.

The hollow construction allows these plugs to compress for a snug fit in threaded and unthreaded holes of varying diameters. Good for electroplating, paint baking, and powder-coating applications, they withstand temperatures up to 450° F.
