Use these fittings for low-pressure applications in noncorrosive environments.

Also known as Schedule 40, this steel pipe is designed for low-pressure applications.

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.

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

A plastic sleeve prevents destructive corrosion when connecting different metals.

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

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

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

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.

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

Use these corrosion-resistant fittings in a low-pressure pipe line.

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.

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

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

When space is at a premium choose these compact 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.

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.

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

Typically used with thin-wall stainless steel unthreaded pipe fittings.

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

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

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

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

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

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

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.

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

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

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.

Connect these fittings to Schedule 40 plastic pipe—they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.

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

Connect to CPVC pipe for use in high-temperature plumbing and water supply applications up to 200° F.

Connect these fittings to UV-resistant PVC pipe. Designed for outdoor use, they contain an additive that protects against the damaging effects of ultraviolet light. Fittings are typically used in low-pressure residential and commercial plumbing and water supply applications up to 300 psi.

Use these clamps to connect easy-access UV-resistant polypropylene pipe fittings to pipe. The clamp-together design allows you to access your line for routine maintenance.

Also known as no-hub couplings, these have a one-piece sleeve with a stop in the center, so you know your pipe is always aligned correctly.

Use in medium-pressure applications up to 230 psi.

Twist these fittings onto high-vacuum tubing to quickly make sealed, high-vacuum connections without the need for clamping, welding, or tools.

Also known as I-line fittings, these quick-clamp fittings permit easy access to your line.

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

Individually bagged to prevent contamination, these fittings are suitable for applications that require a high level of cleanliness.

A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications.

Fittings are polished to a32 Ra and under finish on the interior.

Use at pressures up to 4,300 psi.

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

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

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

The flat face of the fitting connects to a tube adapter so you can slide the tubing and fitting sideways to disconnect in cramped spaces. They are also known zero-clearance fittings.

Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

Choose these metal fittings when you need better durability than our plastic push-to-connect fittings.

Crimp these fittings to copper tubing with a crimping tool for a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings.

These Monel fittings have the corrosion resistance to handle hydrofluoric and sulfuric acid. Also known as instrumentation fittings, they include a nut with two sleeves.

Often used in outdoor, damp, and washdown environments, these 316 stainless steel fittings will not corrode from water, salt, or chemicals. The male threaded ends mate with NPT, NPTF, BSPT, BSPP, and other universal threads, so you won’t have to worry about matching exact threads when you’re on the job.

Made of stainless steel, these fittings have better corrosion resistance than brass fittings.

Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 150 psi.
