Abstract
A corrugated pipe adapter for providing a sealing surface on a corrugated pipe includes a generally cylindrical sleeve having a generally smooth outer clamping surface and at least one protrusion. The protrusions include side walls and an arched structure between the side walls. The protrusions extend from an inside of the generally cylindrical sleeve. The side walls move outwardly against the corrugations on the corrugated pipe when pressure is applied to the generally smooth outer clamping surface.
