Abstract
An adapter for rotatably connecting a sprinkler head to a water-transporting standpipe having a cylindrical upper end. The adapter includes three parts: a cup-like base adapted to rest on the upper end of the standpipe in sealed fashion, a male stem adapted to rotatably and scalingly seat in the cup-like base, and an oversleeve adapted to fit over the stem and the base and to be locked to the upper end of the standpipe by threaded connection such that a portion of the male stem protrudes from the oversleeve to be secured to the sprinkler head for rotation therewith. The adapter is sealed at several points internally to positively prevent water leaks, and is easily disassembled for replacement, repair, or cleaning, by hand or with simple hand tools, since no permanent connection is required between the adapter, the standpipe, and the sprinkler head.
