Adapter pipe fitting for sprinkler or drip-type irrigation systems

摘要

Adapter pipe fittings for sprinkler or drip-type irrigation systems are improved by providing take-off fittings that snap into offtake connector members of the pipe body of such an adapter pipe fitting and swivels therein. The offtake portion of such a take-off swivel fitting preferably includes a screw threaded tip backed by a barb for enhancing holding of attached offtake tubing during the swivel action and for enabling selected take-off swivel fittings in manifold type units to be closed off by screwing plugs onto the threaded terminal ends thereof.
