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

Use this pipe in gravity-flow applications both above and below ground.

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.

These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

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

Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps.

Also known as luer lock couplings, these consist of a plug and socket that connect with a half turn. Use in low-pressure applications up to 30 psi.

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings.

These fittings include a nut with a built-in sleeve, so there’s no need to remove the nut for assembly.

Use these fittings to make leak-resistant connections without threading or soldering. Slide them over tubing and turn the end nuts to compress the gasket.

Thicker walls make these fittings—sometimes called flareless or bite fittings—withstand about twice as much pressure as standard compression fittings, so they’re good for hydraulic power applications.

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.

A single sleeve (ferrule) compresses the tubing as you tighten the nut on these fittings, creating a strong seal. They are brass for good corrosion resistance.

These fittings include a nut with a built-in sleeve (ferrule), so there’s no need to remove the nut for assembly.

Made of acetal, these compression fittings are lighter in weight than metal compression fittings and won’t absorb moisture when used in wet environments.

Lighter in weight than metal quick-disconnect couplings, these couplings are plastic.

Couplings can handle pressures up to 250 psi.

These plastic compression fittings meet NSF/ANSI Standard 51 for food contact.

Fittings have a sleeve that bites into tubing as you tighten the nut to form a seal in applications up to 120 psi. Also known as flareless fittings.
