Abstract
A pneumatic test plug and inflation assembly for the same are provided. The pneumatic test plug may include an inflatable bladder formed by a bladder wall that is elastically deformable, the bladder wall having at least one open end. A housing may be disposed in the open end of the bladder wall, the housing having a mounting surface. An inflation valve may be mounted to the mounting surface, with the inflation valve having an interior end in fluid communication with an interior area of the bladder. The inflation valve may define a main air passageway through which air is introduced into the interior area. The mounting surface may be recessed into the interior area of the bladder relative to the open end in the bladder wall such that the housing defines a cavity within the inflatable bladder.
