    Drain, Waste, and Vent ABS Pipe Fittings for Chemicals

    These Schedule 40 fittings are an economical option for gravity-flow chemical waste systems. They are ABS plastic, which has excellent strength and impact resistance and good chemical resistance. Fittings meet ASTM D2661, ASTM D3311, ASTM D3965, and ASTM F1498 specifications and testing requirements for material quality and product 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.

    Standard-Wall Plastic Pipe Fittings for Water

    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.
    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: 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.

    Through-wall fittings are also known as bulkhead couplings; they mount through your wall or tank to create an inlet or outlet. When installing, the gasket should be on the inside of the wall.
    Fittings for tanks create an inlet or outlet connection on the surface of any tank, pressure vessel, or drum.

    Through-wall fittings are also known as bulkhead couplings; they mount through your wall or tank to create an inlet or outlet. When installing, the gasket should be on the inside of the wall.
    Fittings for tanks create an inlet or outlet connection on the surface of any tank, pressure vessel, or drum.
    Compression Fitting Connection—Fittings with a compression end create a seal using a gasket and nut instead of cement or thread sealant, so they're quicker to install than socket-connect and threaded fittings. Insert the pipe and turn the end nuts until hand tight—the nuts compress the gasket against the pipe for a leak-resistant seal. This type of connection absorbs vibration and provides flexibility to reduce stress on your line.

    UV-Resistant Polypropylene Pipe Fittings for Chemicals

    Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand a wide variety of acids, solvents, and other harsh substances.
    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.
