Low-Pressure Clamp-On Connectors for Drain, Waste, and Vent

Tighten the bands on these connectors to form a strong seal on pipe or fittings.

Socket end-to-socket end connectors allow you to connect two socket-end (female) fittings without using a pipe; the connectors attach over the end of the fitting. Pipe end-to-socket end connectors connect a pipe to a socket-end (female) fitting. Pipe end-to-corrugated pipe connectors connect a rigid plastic pipe to a corrugated polyethylene pipe; a groove in the coupling matches the groove in the corrugated pipe. They are great for storm and drainage systems.

Saddle-tap adapters allow you to tap into an existing pipeline. They have wraparound clamps that provide nearly 360° contact with pipe; as the clamps are tightened, pressure is uniformly distributed around the pipe for maximum support. To install, shut down your line and drill a hole in the pipe where you want to create a connection. Position the saddle over the hole and tighten the clamps.
