Abstract: A re-useable compression type pipe connector comprises threaded male and female portions, a retaining ring and a sealing ring. The retaining ring has a hollow, truncated cone-shaped body portion with a plurality of circumferentially spaced-apart slits which extend in an axial direction inwardly from the smaller end of the retaining ring to define a plurality of gripping teeth. The sealing ring has a tubular shaped body portion, the axial length of the sealing ring being substantially longer than the axial length of the body portion of the retaining ring. The threaded portion receiving the end of the pipe has an annular inwardly-sloping surface which overlaps a portion of the retaining ring. The outside diameter of the sealing ring is such that the outside surface thereof slidably contacts the annular inwardly-sloping surface to exert an inwardly-directed force on the body portion of the retaining ring when the connector is assembled on a pipe.
