ABSTRACT:
An improved pressure gauge which constantly indicates gas pressure in a line. A tubular adapter is attached in a gas supply line. The adapter is provided with a passage which permits gas to flow into an annular chamber defined between an outer sleeve secured to the line adapter and a tubular plunger. The plunger, an annular seal, and a spring are retained on the adapter by the sleeve. The seal, plunger and spring are arranged concentrically about the adapter. Gas pressure entering the chamber forces the seal to engage the plunger which, when sufficiently high, compresses the spring, moving and exposing the plunger. The outer surface of the plunger is provided with numbers and lines thereon which indicate gas pressure at the gauge.
