ABSTRACT:
An adapter for connecting a plastic pipe system to a metallic pipe system; including an elongated, plastic sleeve having a first end thereof adapted to be joined to a plastic pipe system and a second end thereof adapted to be joined to a metallic pipe system wherein said second end has a flange formed as an integral part of said plastic sleeve. A gland means is used to attach the plastic sleeve to the metallic pipe system wherein the gland means is adapted to exert longitudinal pressure on said flange. The invention provides pressure sealing and restraint against axial pull-out that would result in the loss of the pressure seal.
