ABSTRACT:
Adapter pipe fittings for sprinkler or drip-type irrigation systems are improved by providing a two piece pipe fitting, a manifold piece that snaps into a body piece and swivels therein. Such adapter pipe fittings are often required to be installed adjacent to a sidewalk, wall, fence, or other like obstruction whereby there is restricted clearance especially if the pipe fittings has laterally projecting offtake connector members extending therefrom. The fitting is especially well adapted for installation at sites where there is restricted clearance because the body piece can swivel about the manifold piece and the manifold piece is therefore not required to turn while the adapter pipe fitting body piece is being screwed onto an underground piping system.
