Low-Pressure Clamp-On Connectors for Drain, Waste, and Vent
To make installing and maintaining systems easy, these connectors come with clamps that form a strong seal on pipe and fittings once tightened.
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.
