    About Pipe and Fittings

    Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

    Polypropylene Barbed Pipe Fittings for Chemicals

    Made of polypropylene, these fittings stand up to acids, solvents, and other harsh substances. Also known as insert fittings, they have a barbed end that slides into semi-flexible plastic pipe and secures with a clamp (sold separately). You don’t need to wait for cement to dry, so they’re quicker to install than socket-connect fittings. Polypropylene fittings have better flexibility than nylon fittings to accommodate movement and vibration without cracking. They also have better moisture resistance, so they won’t soften or lose strength over time. All meet ASTM D2609 specifications.
    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.

    High-Purity Polypropylene Pipe Flanges for Drinking Water

    The inside of these flanges won’t leach contaminants into your line or accumulate particles—they’re polished to an ultra-smooth 12 Ra finish, which also makes them easy to clean. Made of polypropylene, they resist organic solvents, acids, and alkalis better than CPVC pipe flanges. Bolt two same-size flanges together with a gasket (not included) to create an access point in your line. These flanges meet NSF/ANSI 61 for use with drinking water, and they’re FDA compliant for direct contact with food. They also meet ASTM requirements for material and performance, and ISO requirements for dimensions.
    Also known as lap-joint flanges, they connect to pipe with stub-end straight adapters (not included). Slide the stub end adapter into your flange and weld to your pipe with socket fusion. Since the flange isn’t welded to the pipe, it can be disconnected easily for cleaning and inspecting.
    Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.

    NSF/ANSI 61—To adhere to safety standards for drinking water systems, use pipe that meets NSF/ANSI 61.
