Use these barbed pipe fittings in residential and commercial plumbing and water supply applications. Also known as insert fittings, they have a barbed end that slides into semi-flexible plastic pipe and secures with a clamp (sold separately). Since you don't have to wait for cement to dry, they're quicker to install than socket-connect fittings. They meet ASTM D2609 specifications for barb dimensions.

To prevent leaks in threaded connections, apply a sealant to the male threads. Threaded connections can be taken apart as needed for maintenance and repair. For metal threads, use PTFE tape. For plastic threads, apply a non-hardening, plastic-compatible sealant. Tape or sealants with PTFE are not recommended for plastic-to-plastic connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

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

Note: Barbed pipe fittings are measured by pipe size, which is not an actual measured size, but rather an industry designation.

Also known as Pressure Class 150 flanges, these flanges have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. They meet NSF/ANSI 61 for drinking water. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. All are PVC, which has good corrosion resistance. Some are also glass filled for extra durability. They meet ASTM D1784 specifications and testing requirements for material quality.

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.

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

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.
