Abstract
A pipe fitting, useable in the installation of a sprinkler head, includes (a) a body having an open upstream end and an open downstream end, the downstream end having internal threads capable of accepting a threaded male fitting, the body defining an gasket retention area located upstream of the internal threads; and (b) an gasket disposed within the gasket retention area. The gasket retention area and the gasket are chosen so that a threaded male fitting threadedly disposed within the downstream end of the body can be rotated within the downstream end of the body 360° while remaining liquid tight for pressures in excess of 300 psig.
