ABSTRACT:
Mating halves of plastic composition form a tapping sleeve service connector for mounting a branch connection on an inservice plastic gas main. A tapping tool supported in communication with the branch outlet is provided in one of the sleeve halves. Emplaced lining the internal pipe gripping surfaces of the sleeve halves is a dual faced, open mesh, basket woven fabric containing a random distribution of particle abrasive bonded on each of the faces. The particle abrasive is of a relatively harder composition than the plastics of either the service connector or gas main to effectively penetrate or imbed in the opposed surfaces of each when the sleeve halves are assembled in place. By being imbedded in this manner the abrasive fabric acts to secure and prevent relative rotational slippage between the service connector and pipe on which it is mounted.
