Low-Pressure Clamp-On Connectors for Drain, Waste, and Vent
Pipe End x Socket End
To make installing and maintaining systems easy, these connectors come with clamps that form a strong seal on pipe and fittings once tightened.
Straight offset reducers connect one pipe to a smaller-diameter pipe, keeping your pipes aligned for obstruction-free flow in either direction. They are also known as eccentric reducers.
Pipe end-to-socket end connectors connect a pipe to a socket-end (female) fitting.
Connectors with a stainless steel sleeve reinforce the connection to increase shear strength.

Cast Iron-to-PVC Pipe Adapters for Drain, Waste, and Vent
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.
