Yellow Jacket, 69044, 3-1/8" Vacuum Gauge 0-30 inHg/760-0 Torr (mm)
Mechanical vacuum gauges for system installation. Bourdon tube type gauge. 1/8" NPT Male bottom fitting.
CAUTION: Handle gauges carefully to assure full service life. Dropping, pressurizing and rough handling reduce their life.
Full range mechanical bourdon tube gauges for determining system vacuum. Much more accurate than a compound gauge. All gauges are 1/8" NPT Male bottom connection. 3 - 1/8" gauges are larger to show vacuum more accurately in inches of mercury and Torr (or millibar). 1 - 1/2" gauges are used on Yellow Jacket vacuum pumps.
CAUTION: Vacuum gauges must be handled carefully. Dropping, pressurizing and rough handling reduce their life.
