    About Pipe and Fittings
    industrial info icon

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

    High-Purity Polypropylene Pipe Fittings for Drinking Water

    The inside of these fittings 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 fittings. These fittings 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.
    Connect them to pipe with socket fusion welding for a strong, permanent bond. Use a socket fusion tool with a heater bushing (sold separately) that matches your pipe size. 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.

    Adapter

    Stub-end straight adapters are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.

    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.

    Adapter

    Stub-End Fitting Connection—Stub-end flanges are also known as lap-joint flanges. Use them with a stub-end straight adapter (not included). The stub-end straight adapter slides into the flange and welds to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily for frequent cleaning and inspecting.
    NSF/ANSI 61—To adhere to safety standards for drinking water systems, use pipe that meets NSF/ANSI 61.

    Adapter

    Stub-end straight adapters are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.

    Stub End with

    Flange

    The inside of these pipe stub ends 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 stub ends. These stub ends 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.
    Connect them to pipe with socket fusion welding for a strong, permanent bond. Use a socket fusion welder with a heater bushing (sold separately) that matches your pipe size.
    Pipe stub ends connect flanges to pipe. Slide the straight end into a flange and fuse the stub end to the pipe. Since the flange isn’t fused to the pipe, it can be disconnected easily for cleaning and inspecting.
    Warning: Never use plastic pipe stub ends and pipe with compressed air or gas.
