Our all stainless steel glycerin oil filled vacuum gauges are some of the highest quality gauges available. The gauges feature an NPT stainless steel lower mount connection, bourdon tube and movement, which makes them even more resistant to corrosion than their brass connection counterparts. Also known as "bottom" mount, these gauges are cased in stainless steel and liquid filled to help correct the effects of vibration and pulsation.
The gauges are available in both vacuum and compound (boost) ranges. They are good for gas, water, oil and diesel.
