ABSTRACT:
A method is shown for installing a pipe gasket within the bell end of a pipe section. The bell end is oriented along a horizontal work axis. The annular gasket is inserted within the mouth opening of the bell end of the pipe. The gasket is oriented at an oblique angle with respect to the horizontal axis, whereby a leading edge of the annular gasket moves past the annular groove provided in the bell end and a trailing edge of the gasket engages the annular groove. A retracting force is exerted on the gasket by pulling the leading edge backwards in the direction of the mouth opening of the bell end of the pipe until the gasket snaps into a lock-in position within the annular groove. The gasket body has an embedded relatively rigid ring which is precisely located to ensure that the gasket, once in snap-fit position, is securely retained within the gasket groove and cannot be displaced.
