Abstract:
A simple-to-use apparatus install around a pipe which passes through or under a building partition and maintains the structural integrity of the pipe in accordance with a typical building codes. More specifically, the apparatus preferably includes an inner sleeve composed of an elastomer (e.g. synthetic or natural rubber) or a foam-like material that surrounds the entirety of the portion of a pipe or conduit that passes through the building partition. The inner sleeve is entirely surrounded by an outer sleeve composed of a harder material than the inner sleeve. The inner sleeve and the outer sleeve can each be formed by extrusion, molding, or any other conventional manner. The inner sleeve maintains a circumferential spacing between a pipe passing through the apparatus at the outer sleeve thereby isolating the pipe from forces exerted by the building partition.
