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

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

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.

Also known as Pressure Class 125 flanges, these are for use in low-pressure applications. Flanges are aluminum, which is lightweight with good corrosion resistance.

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

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.

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings.

Thick walls give these Schedule 80 fittings excellent strength.

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 60 psi. Also known as insert fittings, these slide into semi-flexible plastic pipe and secure with a clamp.

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.

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.

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.

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.

Use these clamps to connect easy-access CPVC pipe fittings and pipe.

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 corrosion-resistant plastic, these fittings won’t deteriorate when used in oil applications. They have high strength and impact resistance.

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.

With thinner walls than Schedule 40 fittings, these are lighter in weight and have more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines. They are also known as SDR 35 fittings.

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.

These manifolds have two separate sections inside, so you can run two different substances through them without worrying about them intermixing. Also known as headers.

Unlike other manifolds, which have an inlet on either end, these have one inlet on the opposite side from the outlets. This design allows air or fluid to follow a straight path, improving flow through your system. Also known as headers.

A great solution when space is at a premium, these manifolds are less than an inch in height, yet allow you to supply up to 12 lines from one distribution point.

With outlets on the side instead of on top, these manifolds have a lower profile than rectangular manifolds and fit well in cramped spaces. Use them to distribute air or fluid to three locations from a single supply source.

A built-in shut-off valve stops airflow when the fittings are disconnected from tubing.

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

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.

A 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube fittings.

The threads on these fittings mate with NPT, NPTF, BSPT, and BSPP threads.

Use at pressures up to 150 psi.

An all-metal body and built-in tube support or dual seals allow these fittings to handle the highest pressure ratings of all our push-to-connect tube fittings.

Barbs grip onto tubing.

Silver ions in the material help inhibit the growth of bacteria, mold, fungi, and other odor-causing microbes.

The nickel plating on these fittings provides better corrosion resistance than unplated brass fittings.

Color-code fittings for easy identification. These aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

You don't need a clamp to secure these fittings to tubing. They have a nut on the barbed end that tightens to holds the tubing in place.

A built-in tube support slips inside the tubing to prevent collapsing and provides a sturdy connection for an extra-tight seal.
