1. A pulsation throttling device for a pressure gauge comprising:

  • (a) an elongated cylindrical plug adapted for a snug fit in a bore communicating with the inlet to the sensing mechanism of a pressure gauge;

    (b) said plug including two axially contiguous portions including an upstream portion cooperating with the bore surface thereat to define an annular flow clearance therebetween, and a downstream portion cooperating with the bore surface thereat to define a selective flowpath therebetween effective to dampen pulsation in the flow being conducted in said bore; and

    (c) said annular flow clearance of said upstream portion having a radial dimension equal to or less than the minimum clearance afforded by the flow path of said downstream portion.
