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

    Drain, Waste, and Vent PVC Pipe Fittings for Joining Metal to Plastic

    These adapters connect PVC waste pipe to cast iron pipe without adding bulk. Instead of securing pipes together from the outside like clamp-on couplings, these flexible adapters fit into cast iron pipe to create a tight compression seal. Adapters should fit tightly—tap with a mallet to install. Made of PVC, these fittings won't corrode when exposed to water.
    Warning: Never use plastic pipe fittings, flanges, and pipe with compressed air or gas.
