Ashcroft 451279 Process Pressure Gauge

This gauge measures process pressure from 0 to 160 psi with a 4 1/2 in dial. It is built for technicians who need accurate readings in industrial or commercial systems. The phenolic case and glass lens suit demanding environments. Accuracy is rated at +/- .5 percent across the full range.

NPT bottom connection limits orientation

The 1/2 in male NPT connection sits at the bottom of the case. This fixes the mounting angle and requires a compatible female port. No field-fill option means the gauge arrives ready to install but cannot be liquid-damped on site. The 5.375 in bolt circle sets the panel cut-out pattern.

Phenolic case and glass lens for durability

The black phenolic case resists chemicals and impact better than many plastics. A glass lens protects the white dial from scratches and solvents. With no vibration resistance or dampening listed, the gauge suits steady-pressure applications. The unit is not IP or NEMA rated, so seal the panel cut-out if moisture is present.

Questions about this item

Should I choose a different pressure range or dial size for my application?

This model is fixed at a 0 to 160 psi range with a 4 1/2 in dial; select another Ashcroft gauge if your process requires a different span or case diameter.

What does the +/- 0.5 percent accuracy mean for actual readings on this 0 to 160 psi gauge?

Accuracy is expressed as a percentage of the full 160 psi span, so the maximum permissible error is half a percent of that span across the entire dial.

How does the 1/2 in NPT bottom connection limit installation options?

The male 1/2 in NPT bottom mount fits standard female ports and orients the dial vertically; it cannot be panel-mounted without an adapter because the bolt circle is 5.375 in and the case is not field-fillable.
