ABSTRACT:
A pressure tap assembly for connection between a pipeline flange and a manifold and/or transmitter in which can transmit the load from a threaded end of the tap to the body of the tap. In one embodiment the tap is provided with a tap body having an integral stabilizing flange. By the use of a force providing device the stabilizing flange is forced in a direction away from the pipeline flange thereby reducing the load on the threads on the threaded end of the tap. A combination of a stabilizing nut and stabilizer base can be used to provide the force.
