Ashcroft 451279 Process Pressure Gauge

The Ashcroft 451279 is a new process pressure gauge built for industrial pressure monitoring. It suits technicians and engineers who need reliable readings in demanding environments. The stainless steel finish and phenolic case provide durability for field use.

Accuracy ±0.5 Percent Full Scale

The single specification that decides fit is the accuracy of ±0.5 percent across the 0 to 1000 psi range. This precision level meets standard industrial calibration requirements. Verify that your application tolerances align with this figure before purchase.

Dry Dampened Vibration Resistance

The gauge uses a PLUS! Performance dry dampening feature to resist vibration without liquid fill. The glass lens and bottom-mounted 1/2 inch NPT male connection support stable operation. The case is not IP or NEMA rated for ingress protection.

Questions about this item

What does the +/- 0.5 percent accuracy mean when the gauge is installed on a live process line?

The reading will stay within half a percent of the true pressure across the 0 to 1000 psi span, so at full scale the maximum error is five psi.

How does the 1/2 in male NPT connection limit the fittings I can use?

It accepts only 1/2 in female NPT threads, so any adapter or valve must match that exact thread form and size.

What clearance does the 4 1/2 in phenolic case with bottom connection need for panel mounting?

The case diameter requires a cut-out slightly larger than four and a half inches, and the bottom-mounted stem needs room behind the panel for the 1/2 in NPT connection.
