Abstract
A lockable pipeline seal, pipeline sleeve, and sealed pipeline connection for a pipeline. The pipeline seal includes a ring-shaped body having a head along a first ring end and a tail along a second ring end of the ring-shaped body, with a body portion therebetween. The ring-shaped body has an outer surface and an inner surface along its periphery. A deflection surface and abase surface are defined along the outer surface. The deflection surface is at an angle to a horizontal axis of the ring-shaped body, and a recessed grip is defined along the inner surface. The ring-shaped body is compressible such that, when the pipeline seal is installed between the pipeline sleeve and the pipeline pipe, the deflection surface is urged against the pipeline pipe and the recessed grip grippingly engages the pipeline sleeve whereby a locked seal is formed between the pipeline sleeve and the pipeline pipe.
