ABSTRACT:
Dampening apparatus for a pressure gauge in which a short length of sleeve, ferrule, hub or thimble encircles the pointer shaft in a close but loose fit relation and is packed with a high viscosity fluid such that it will serve to decelerate and cushion any sudden shock or pulsation force that would otherwise be transmitted to the pointer shaft.
