This is the most common form of corrugated metal pipe joining system.

The MarMac CMP O-ring gasket can be used in conjunction with a smooth or corrugated external sleeve that generally indexes with pipe corrugations to provide some mechanical interlock between the band and the pipe. With the addition of our O-Ring gaskets and other products, this joining system can provide varying degrees of water tight performance. Pipes with this joint are typically used in culvert, detention/retention, and storm sewer applications.

We provide all sizes of O-Ring gaskets from 12”-36” using 13/16” diameter material and 42”-144” using 7/8” material.

We also carry 1/8” 70D EPDM cord.
