A pipe fitting fabricated out of an electrically non-conductive material for use in the coupling of pipe sections, the fitting being provided with integral conductor means for bonding, grounding, or shunting purposes. In this design, the conductor is a metal strap or strip which extends across the fitting body to the coupling ends thereof. The bottom portion of the conductor strap is substantially embedded in the wall of the fitting and the exposed surface of the strap is provided with sharp edges or similar means which are used to scrape clean the faying surface in the bore of the pipe when a connection therewith is being made to insure a good electrical contact therebetween.
