Abstract
A dampening apparatus for a pressure gauge in which a housing secured to the amplifier of the pressure gauge encircles the pointer shaft in a close but loose fit relation so as to define a controlled clearance packed with a high viscosity dampening agent such that it serves to decelerate and cushion any sudden shock or pulsation force that would otherwise be transmitted from the pointer shaft to a pointer registering values of pressure of fluid pressure being monitored.
