Corrugated Pipe Adapter

The corrugated pipe adapter gasket is a rubber adapter ring that fits closely into the corrugation of the pipe, creating a smooth exterior diameter for connecting the pipe to a manhole or other types of structures.

Kwik Seal

Kwik Seal is a precisely sized compression connector (pipe to manhole connector) made to fit in a cored or cast opening. The connector is placed into the opening and the pipe is pushed home. This creates a watertight seal when the connector is compressed around the pipe OD and is deformed against the manhole opening. The sealing is similar to how a pipe gasket seals pipe joints.
