Abstract:
A pipe coupling for connecting adjacent pipes. The pipe coupling has a connection type at each end that may be male or female. A female end may have an interior surface defining a receiving chamber. An interior circumferential groove is formed in the interior surface in which a band is seated. A plurality of rigid fingers is extends from the band into the receiving chamber. The receiving chamber receives a male end of an adjacent pipe, the male end having an exterior surface. An exterior circumferential groove is defined on the exterior surface to receive the plurality of rigid fingers. A variety of connection types and combinations are possible. The female end may define a sight window to permit viewing of the position of a male end of an adjacent pipe. The receiving chamber may have a reduced diameter proximate to the middle of the coupling to improve sealing.
