ABSTRACT:
A coupling for joining sections of tubular pipe together end to end into a continuous length includes a tubular connector having an outside diameter substantially equal to the inside diameter of the pipe and having a protruding annular shoulder of arcuate cross section located intermediate its ends. The adjacent ends of the pipes are placed over opposite ends of the connector and pressed together, flaring their terminal portions outwardly where they abut, substantially coplanar with the diametric center of the shoulder, frictionally joining both sections of pipe to the connector. A metallic colored, silicone sealant is coated over the confronting raw ends of the pipes to provide a low maintenance seal which protects the joint from deterioration.
