Pipe fitting |
摘要 |
A pipe fitting formed of resilient material having two or more end portions disposed at a predetermined angle to each other. A firm metallic sleeve is positioned about the resilient plastic material and a clamp is afforded at each of the end portions. Each such end portion is adapted to receive the end of a threaded or unthreaded pipe and is formed with internal annular ribs for sealingly engaging the pipe. The central portion of the fitting is provided with a thicker wall section so that the internal diameter thereat substantially coincides with or equals the internal diameter of the pipe.
