Seal unthreaded pipe ends. A band clamps over the outside of your pipe to secure these plugs. They’re made of rubber that withstands stretching and compression from frequent maintenance or long-term installations.

To make installing and maintaining systems easy, these connectors come with clamps that form a strong seal on pipe and fittings once tightened.

Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

Create an access point in a low-pressure pipeline. Bolt two flat-surface flanges or two raised-surface flanges of the same size together with a gasket (not included). Flanges are steel and perform best in noncorrosive environments.

The industry standard for residential and commercial low-pressure plumbing and water supply lines. Connect these fittings to Schedule 40 pipe. Made of plastic, they’re lightweight and naturally rust resistant.

Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.

Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

Connect these fittings to Schedule 80 pipe. Thicker and stronger than standard-wall fittings, they can handle industrial applications such as water processing, wastewater treatment, and irrigation. Fittings are plastic so they're naturally rust-resistant. They meet ASTM specifications and testing requirements for material quality.

Note: For fittings that are not rated for pressure, you can use the pressure rating of the plastic pipe as a reference. Threaded fittings are limited to 50% of the rated pressure of the pipe.

Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

Forged for extra strength, these heavy duty flanges create an access point in high-pressure lines. To connect, bolt two flat-surface flanges or two raised-surface flanges of the same size together with a gasket (not included). Flanges are made of steel and best for noncorrosive environments.

Create an access point in a low-pressure pipeline. Bolt two flat-surface flanges or two raised-surface flanges of the same size together with a gasket (not included). Flanges are stainless steel for excellent corrosion resistance.

Conform to wide and out-of-round pipes with these inflatable plugs. Also known as pneumatic plugs, they're designed for temporary seals since they can lose pressure over time. They’re better for lower-pressure applications than water-inflatable plugs. Inflate them with a hand pump; an air compressor may overinflate the plug and cause damage.

Plugs with a chain or eyebolt can be tethered through either so they don't get lost or stuck in your pipes during installation. For easy removal once testing is complete, pull on your tether.

Conform to wide and out-of-round pipes with these inflatable plugs. Also known as pneumatic plugs, they're designed for temporary seals since they can lose pressure over time. Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve pressure while testing.

Inflate with a hand pump (sold separately); an air compressor may overinflate the plug and cause damage. Tether the plugs using either the eyebolt or chain/ring so they don't get lost or stuck in your pipes during installation. Pull on the tether for quick and easy removal once testing is complete.

Also known as Pressure Class 150 flanges, these have thick, strong walls to handle industrial plumbing and water supply applications, such as water processing, wastewater treatment, and irrigation. They also meet NSF/ANSI 61 for drinking water. Use these flanges to create an access point within a line. To install them, bolt two of the same size together with a gasket (not included). Flanges are made of plastic, so they're naturally rust resistant.

Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.
