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.

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

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.

Crimp these fittings onto steel pipe to form a tightly sealed 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. Slide the pipe into the socket and weld.

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

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

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

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

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

Also known as no-hub pipe fittings and soil pipe fittings, these fittings are for use in gravity-flow applications both above and below ground.

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.

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.

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.

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

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

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

Thick walls give these Schedule 80 fittings excellent strength.

Designed for medium-pressure applications, these fittings have better strength than our low-pressure aluminum pipe fittings.

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.

Watch water flow through your line. These fittings are compatible with Schedule 40 pipe, the industry standard for residential and commercial low-pressure plumbing and water supply.

Connect to CPVC pipe for use in high-temperature plumbing and water supply applications.

Also known as manifold flange fittings, these have a clamp-together design that lets you access your line for routine maintenance. Fittings resist acids, solvents, and other harsh chemicals. They won’t deteriorate when exposed to the damaging effects of ultraviolet light, so they’re suitable for outdoor use.

These fittings have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. They are commonly used in metal surface treating applications, plating solution lines, and other chemical process applications. Reinforced with layers of fiberglass, they have better strength and durability than any of our other pipe fittings for chemicals.

The inside of these fittings won’t leach contaminants into your line or accumulate particles—they’re polished to an ultra-smooth 12 Ra finish, which also makes them easy to clean. Made of polypropylene, they resist organic solvents, acids, and alkalis better than CPVC fittings.

Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges are an economical option for gravity-flow chemical waste systems. They are ABS plastic, which has excellent strength and impact resistance and good chemical resistance.

Made of polypropylene, these gravity-flow fittings withstand organic solvents, such as acetone, that would dissolve CPVC pipe. They also stand up to highly corrosive acids, such as hydrochloric acid, and alkalies.

Bolt two same-size flanges together with a gasket to create an access point within a line. Also known as Schedule 40 flanges, they are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth.

Also known as KF, QF, and NW fittings, these fittings are for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases.

For applications that require an extra level of cleanliness, these fittings are individually bagged to prevent contamination.

The male pipe threads on these fittings have a sealant applied for extra protection against leaks.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included.

When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.

The sleeve in these fittings is rubber instead of metal, so it cushions the tubing and absorbs vibration while creating a tight seal.

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on steel tubing that is flared to 37°.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal.

Connect high-pressure brake lines with fittings that won’t crack in frigid temperatures. Often used on commercial trucks and trailers, these fittings meet Department of Transportation FMVSS 571 safety standards.

Designed for use in welding applications, these fittings are flame retardant.

Fittings can withstand temperatures up to 200° F.

Made of polypropylene, these cam-and-groove couplings are lighter in weight than metal cam-and-groove hose couplings.

Fittings have sharp barbs that grip push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip. Use in low-pressure hydraulic applications up to 350 psi.

With an easy-to-cut hose and push-to-connect fittings, you can install a compressed air line system in just a few hours.

Join pieces of conduit.

Attach conduit to a knockout in an outlet box or enclosure.

Join duct and fittings with quick-release clamps for faster disassembly and cleanout than other duct systems.

Fittings have gaskets which create a tight seal—you don't need to seal joints with coating or tape.

Often used in tight spaces, such as in walls and ceilings, rectangular duct allows you to select larger sizes without increasing duct height.
