ABSTRACT:
A universally angularly adjustable sealable pipe coupling comprises a first coupling member including a first outer internally threaded pipe engaging section and an inner socket section of increasing radii of curvature approaching its open end and a second coupling member including an inner ball section with inside and outside faces of increasing radii of curvature approaching an open free end, the ball section registering with the socket and a second outer internally threaded pipe engaging section. A tubular plastic locking member includes a locking section having a curved outside face engaging the ball section inside face and a coaxial tubular shank slideably engaging the inner end of the first pipe engaging section. The first and second coupling members are relatively universally angularly adjustable and are locked in the present position by tightening a pipe in the first coupling section to advance the locking member.
