A stab joint, pipe assembly, and method of forming a seal between a corrugated pipe and a bell utilize an annular gasket secured to a corrugated pipe through the use of a compression strap that applies a compressive force to the gasket to form a seal between the gasket and the outer engagement surface of the pipe. The annular gasket overlays an adjacent crest and valley on the outer engagement surface of the pipe and is formed of a compressible material having an uncompressed radial thickness that is greater than the radial distance between the inner engagement surface of the bell and a crest on the outer engagement surface of the pipe. When compressed by the compression strap, at least a portion of the annular gasket has a diameter that is greater than that of the strap such that the annular gasket forms a seal with the inner engagement of the bell when the pipe is inserted into the bell.
