ABSTRACT:
The gas riser connects underground natural gas service lines, particularly plastic service lines, with above ground meters and the like. The riser includes a conduit or plastic tube which has first and second ends. An annular collar is swaged onto the exterior of the conduit adjacent its first end. An annular resilient seal frictionally engages the exterior of the conduit abutting the annular collar. A retaining ring is slidably disposed on the exterior of the conduit abutting the resilient seal. A connector is integrally affixed to the second end of the conduit for connecting it to a service line. A tubular element or iron pipe has an internal bore, an annular projection into the internal bore, a tapered portion adjacent the projection, and threads at one end for connecting it with the meter. The first end of the conduit is disposed in the internal bore with the retaining ring engaging the annular projection, the resilient seal engaging the tapered portion, and the annular collar pressed into engagement with the tapered portion and compressing the resilient seal against the retaining ring, the O.D. of the conduit and the I.D. of the iron pipe.
