The Mastercool 98065 Analog Vacuum Gauge with 1/8" NPT Male Thread Fitting is designed with the highest quality to provide accurate readings every time. The bourdon tube type analog vacuum gauge is used for determining system vacuum. Barometric pressure compensation allows for the most accurate reading regardless of altitude or local weather conditions.

The 98065 handheld analog vacuum, class 1.0, gauge is equipped with a 1/8" NPT male thread fitting that allows for mounting directly to a manifold block.

The large 80mm size makes the 98065 gauge easier and more accurate to read than smaller gauges. It is equipped with an indicator needle to mark pressure for testing, providing a backup in case you forget to write the pressure down. You can see if the pressure has changed with a quick glance.
