Abstract
A two-piece flange adapter including two identical flange parts. Each flange part has two ends, with each end having a planar mating surface disposed at each end of the channel disposed on an inner diameter surface of the flange part. A projection extends from one planar mating surface and is formed to continue the channel for a predetermined distance past the planar mating surface. The other end of the flange and channel define a groove having a depth that accepts the projection of a mating flange part to form a complete channel. A gasket having a cross-sectional area with an internal cavity is compressively disposed in a pocket defined by the channel and the mating pipes. The cross-sectional area of the gasket occupies less than 87% of the pocket and can also occupy approximately 82-84% of the pocket.
