NPC Kor-N-Seal II: 306 Series


		The 306 Series Pipe-to-Manhole Connector is designed to fit larger pipes into the smallest possible manhole. When you put a hole in a manhole, the sides of the hole are further back than the top and bottom because of the curvature of the manhole. The patented 4 inch wide stainless steel korband is able to overcome the curvature of the manhole and provide a watertight seal.
As an example, where a regular boot would require a 60 inch manhole for a pipe with a 30 inch O.D., the 306 Series allows you to use a standard 48 inch manhole with a 5 inch wall. This is possible because of the 4 inch wide Korband.
