<p>An O-ring has a flange which includes a plurality of slots, such that, whe n inserted into an annular groove of a pipe fitting before crimping, the slots allow the flow of fluid therethrough, such that an installation would not pass pressure tes ts until such time as a proper crimp has been made. Such a design allows the use of conventional push-on pipe connections by utilizing a unique O-ring seal which works in conjunction with standard push-on crimp-type pipe fittings and conventional crimping too ls for subsequently sealing the connection. The O-ring is either circular or elliptical in cross section and the slots define equally spaced annular segments.</p> |
