Test and Measurement Vacuum Gauge

The Value Brand vacuum gauge provides electronic pressure testing with a 3-1/2 inch dial that reads from -30 to 0 in Hg and a secondary scale of -100 to 0 kPa. Its 304 stainless steel case and wetted parts resist corrosion in automotive and industrial environments. Accuracy is rated at +/-3-2-3 percent across the range.

Technicians needing basic vacuum verification

This gauge suits mechanics and engineers who require a panel-mountable instrument for routine vacuum checks on HVAC, brake or fuel systems. It is not liquid filled, so users who need vibration damping or pulsation protection should look at a different design. The bottom 1/4 inch MNPT connection limits orientation options for tight installations.

No bundled accessories or software

The unit ships as a standalone gauge without a calibration certificate, mounting hardware or carrying case. Buyers must supply their own fittings, sealant and any documentation required for quality compliance. The absence of included extras keeps the initial cost lower but adds separate procurement steps.

Questions about this item

What thread size does the 1/4 in MNPT connection on this vacuum gauge require on my fitting?

The gauge has a 1/4 in MNPT bottom connection, so you need a matching 1/4 in FNPT fitting or adapter for a leak-free seal.

Will the 304 stainless steel case and wetted parts resist corrosion if I keep using my older brass manifold?

Yes, the 304 stainless steel case and wetted parts are corrosion-resistant and compatible with brass fittings in typical vacuum service.

How do I verify the gauge reads correctly after installing it on my system?

Apply a known vacuum source; the needle should move smoothly toward -30 in Hg and the kPa scale should track toward -100 kPa within the stated accuracy.
