GOGO MECHANICAL VACUUM GAUGES 3-1/8" GG4029

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 mbar.
CAUTION: Vacuum gauges must be handled carefully.
Dropping, pressurizing and rough handling reduce their life.
