1.The pipe joint or coupling is applicable for use only with pipes composed of comparatively hard thermoplastic synthetic resin composition. 2. The pipe joint or coupling is also suitable for use with metal pipes.3. If composed of any material the sealing ring will be contracted into good sealing engagement with the pipe. 4. The rings are composed of suitable metals to suit the material of which the pipe is composed. 5. There shall be a difference of approximately 2 ½  between the tapes of the two tapering surfaces. 6. A pipe joint doesnt comprise a sleeve nut.7. The pressure ring is formed with a tapered surface corresponding with the tapering surface on the interior of the sleeve nut. 8. The pressure ring is preferably formed with one cylindrical face.
