Abstract
A pipe coupling for attachment to a pipe includes a sleeve. One end of the sleeve is configured to receive a pipe end. The pipe coupling also includes an annular gasket disposed within the end of the sleeve for encircling the pipe end. The coupling includes a flanged assembly for compressing the annular gasket to form a seal between the pipe and the sleeve. The sleeve and the gasket are configured so as to define a leak path between an axially inner portion of the gasket and the inner surface of the sleeve, whereby pressurized fluid from the pipe may pass along the leak path so as to pressurize a radially outer surface of the gasket and urge the gasket against the compression flange to enhance the seal between the gasket and the sleeve.
