Ashcroft 451279 Process Pressure Gauge

The Ashcroft 451279 is a process pressure gauge designed for industrial monitoring where reliable pressure indication is required. It suits plant engineers and maintenance technicians who need accurate readings on compatible process lines.

Thermals, noise and power draw

As a mechanical dial instrument, the gauge operates without electrical power and produces no audible noise during use. Its dry PLUS! Performance dampening resists vibration effects on the pointer without requiring fluid fill or external energy.

Build quality and connectors

The phenolic case in black with a glass lens provides chemical resistance and clear visibility of the white dial. A male 1/2 in NPT bottom connection allows direct mounting into standard process ports, while the non-field-fillable design means the unit is sealed for the application as supplied.

Questions about this item

How is the 1/2 in NPT male connection installed on the 451279 gauge?

Thread the 1/2 in NPT male process connection into the matching female port using PTFE tape or pipe sealant on the threads; the common error is over-tightening, which can crack the phenolic case.

What maintenance will the 0-60 psi gauge need over time?

The dry PLUS! Performance dampening requires no fluid refill; periodic calibration checks against a known standard are the only routine upkeep, and the glass lens can be cleaned with a soft cloth.

What is the first limit reached under continuous vibration?

The dry vibration-dampened case protects the movement, but sustained vibration beyond the design intent can still cause pointer fatigue; the +/- 0.5 percent accuracy spec is the first performance limit to monitor.
