Abstract:
A fire sprinkler piping system fitting, comprising:a polymeric body having at least a first tubular branch, a second tubular branch, and a third tubular branch, each of the first, second and third tubular branches extending outwardly from a common junction, the first and second tubular branches being collinear and the third tubular branch being generally perpendicular to the first and second tubular branches, each of the first, second and third tubular branches having a distal end opposite from the common junction; a pair of internally threaded metal inserts, each insert being at least partially molded into the distal end of a separate one of the first and second tubular branches, each of the pair of internally threaded metal inserts having a distal outer surface facing generally away from the common junction, the distal outer surfaces of the pair of internally threaded metal inserts being spaced apart a distance of between three inches and four inches along an axis and adapted to retain respective fire sprinklers at distal ends of the body along the axis so that when the body is disposed between spaced walls, a deflector of each respective sprinklers projects from a surface of each of the walls opposite a wall surface exposed to the body; and the distal end of the third tubular branch having a smooth internal bore to slidingly receive a smooth outer end of a length of pipe.
