Series 7000B Spirahelic® Direct Drive Pressure Gage

4-1/2" Turret Mount Gage, ASME Grades A & 2A

SERIES 7000B Spirahelic® Direct Drive Pressure Gages with turret mount housings feature a triple coil spiral/helical wound Bourdon tube to provide dependable service. Bourdon tube design eliminates gears, springs, linkages and complex movements which can wear and cause inaccuracy or early failure. Series 7000B gages come standard with a dual-size 1/2" male NPT and 1/4" female NPT process connection.
