Ashcroft 451279 Process Pressure Gauge

This Ashcroft process pressure gauge measures from 0 to 300 psi with a 4 1/2 inch dial. Accuracy is rated at +/- 0.5 percent and the case is built from phenolic material. A glass lens protects the white dial face.

Suits technicians needing accurate analog readings

It fits applications requiring a bottom-mounted 1/2 inch male NPT connection and dry vibration-dampened operation. The gauge is not field fillable and carries no IP or NEMA rating, so it is unsuited for environments that demand sealed protection or liquid filling.

Primary pressure range 0 to 300 psi

The 0 to 300 psi range is the single specification that determines whether this gauge matches the process pressure. If the system operates outside this span, a different range must be selected.

Questions about this item

What process connection size and type does the Ashcroft 451279 gauge require on my piping?

It needs a 1/2 in male NPT connection at the bottom of the case.

Will the phenolic case and dry vibration-dampened movement survive on older vibrating equipment?

Yes, the dry PLUS! Performance feature is designed to resist vibration without liquid fill.

How do I verify the +/- 0.5 percent accuracy on the 0 to 300 psi dial after installation?

Compare the white dial reading against a calibrated reference gauge at several points across the 0 to 300 psi range.
