A reinforced pipe fitting has a body with a cylindrical first section and a cylindrical second section. The first section has a first longitudinal axis and the second section has a second longitudinal axis. The side walls of the first section intersect the side walls of the second section at a crotch point disposed within the plane defined by the first and second longitudinal axes. The first section defines a first section crotch area pipe stop having a proximal portion disposed proximate to the crotch point and a distal portion disposed opposite the proximal portion. The average thickness of the proximal portion disposed 15° to either side of the plane defined by the first and second longitudinal axes is greater by about 15% than the average thickness of the distal portion disposed 15° to either side of the plane defined by the first and second longitudinal axes.

A fire sprinkler fitting has a cylindrical body and an insert. The insert has an inner end which is disposed within a proximal portion of the bore, such that the outer end protrudes beyond the open bore end by a distance D. The outer end has internal threads which are sized and dimensioned to accept and retain a fire sprinkler therein. The insert is rotatable within the body without effecting the distance D.
The invention satisfies this need. The invention is an internally threaded insert for use with a polymetric pipe fitting in a fire sprinkler system. The insert comprises an outer side surface, an outer rearward surface and an outer forward surface. The outer forward surface is adapted to retain a fire sprinkler at a forward end of the insert. The outer side surface of the insert is sized and dimensioned so as to closely match the bores of standard polymeric pipe fittings, so as to be capable of being slidably and snugly received into the bores of a standard polymeric pipe fitting. The insert can be conveniently affixed within the bores by non-mechanical means, such as by gluing.
