Panel-Mount Compound Gauge 4 1/2 in

The Ashcroft 0627-0500-0001-60 is a panel-mount compound gauge designed for measuring both vacuum and pressure in a single instrument. It features a 4 1/2 inch nominal dial size with a white dial and glass lens for clear readability. The phenolic/thermoplastic case provides durability in industrial environments while the bottom-mounted 1/2 inch male NPT connection allows straightforward installation.

Replaces separate vacuum and pressure gauges

This compound gauge combines 30 inches of mercury vacuum through 0 to 160 psi pressure in one unit, eliminating the need for two dedicated instruments. The upgrade is worth it when a process cycles between vacuum and positive pressure and panel space is limited. The +/- 0.5 percent accuracy meets typical industrial calibration requirements without the cost of higher-grade test gauges.

Sustained load behaviour

The gauge is not field-fillable and has no dry dampening feature, so the movement responds directly to pressure changes without liquid buffering. Vibration resistance relies on the field-fillable design rather than a factory-filled case, meaning pointer flutter may occur under continuous mechanical vibration. The black phenolic/thermoplastic case resists corrosion during extended exposure to harsh atmospheres.

Questions about this item

What panel cut-out does the 4 1/2 in phenolic case need?

The gauge uses a 1/2 in male NPT bottom connection, so the panel must accommodate that thread size and a bottom-entry mounting hole.

How do I seal the 1/2 in NPT connection without stripping the phenolic housing?

Apply PTFE tape or pipe sealant to the male threads, hand-tighten, then turn one to two full turns with a wrench on the hex flat — not the case.

When should I replace the glass lens or the gauge itself?

Replace if the lens cracks, the pointer sticks, or readings drift beyond the stated +/- 0.5 percent accuracy.
