Abstract
To join two pipe sections carrying fluids that may be at relatively high pressures, a coupling body into which the ends of the pipe sections are inserted has a gasket seal at each end thereof. In order to electrically insulate the sections of pipe from one another, an insulating sleeve is located along a length of the internal surface of the coupling body. An insulating stop member is slidable within the sleeve to separate the ends of the sections of pipe, the stop member being prevented from entering the length of the coupling body that does not have an insulating sleeve. Threads for coupling nuts utilized in achieving the fluid tight seal are formed in the outer surface of the coupling body at each end thereof.
