  • 1/4 NPT bottom connection for direct mounting
  • ±0.25% accuracy with NIST calibration certificate
  • Aluminium case with brass wetted parts

Ashcroft 601082 6-Inch Vacuum Gauge

This Ashcroft 601082 vacuum gauge measures pressure from -30 to 0 in Hg on a 6-inch dial. The aluminum case houses brass and bronze wetted parts with a 1/4 NPT bottom connection. Accuracy is rated at +/- 0.25 percent with a 0.1 in Hg graduation. A calibration certificate with NIST data is included.

Suited for Hydraulic Test and Panel Builds

Technicians testing hydraulic systems or building custom panels will appreciate the large dial and documented accuracy. The gauge is not liquid-filled and cannot be panel-mounted, so installers needing vibration damping or a flush mount should look at alternative models.

Steady Readings During Extended Test Runs

The dry aluminum case and brass internals maintain the stated +/- 0.25 percent accuracy throughout prolonged vacuum checks. Without liquid fill, the pointer responds quickly and does not develop temperature-induced drift during sustained operation.

Highlights

  • 6-inch dial for clear vacuum readings
  • Measures 30 in Hg vacuum range
  • 1/4 NPT bottom connection for direct mounting
  • ±0.25% accuracy with NIST calibration certificate
  • Aluminium case with brass wetted parts

Questions about this item

What size NPT fitting do I need on my system to connect the 1/4 in MNPT on this gauge?

The gauge has a 1/4 in MNPT bottom connection, so your system must provide a matching 1/4 in FNPT port for a direct thread engagement.

Will the brass and bronze wetted parts hold up if the rest of my hydraulic circuit uses steel fittings?

Yes, brass and bronze wetted parts are compatible with typical steel hydraulic fittings and fluid media used in vacuum test applications.

How can I verify the +/- 0.25 percent accuracy after installation?

Apply a known vacuum reference at several points across the 30 in Hg scale and confirm the needle reads within 0.1 in Hg of the reference at each point.
