Socket Recess Pipe Plugs, also referred to as drain plugs or filler plugs, are designed to seal the end of threaded pipes to dead end the flow of fluid. These socket recess pipe plugs are designed to insert into the end of pipe to end the flow. A dry seal plug is one having a tapered (0.750" diametrical per 12" or 0.870" diametrical per 12") thread extending its entire length and designed to have its threads mesh tightly with those of a taper-threaded hole. Both ends of the plug shall be flat and chamfered approximately 45 deg. The chamfer shall extend slightly below the root of the thread, and the edge between flat and chamfer shall be slightly rounded. May be mildly magnetic.
