Ashcroft 4½-inch Process Pressure Gauge

This Ashcroft process pressure gauge measures 0 to 160 psi on a 4½-inch dial with ±0.5 percent accuracy. The case is made from polybutylene terephthalate in black with a white dial and glass lens. A ½-inch male NPT connection is located at the bottom and the unit is not field fillable.

Installation uses a standard ½-inch male NPT thread

The gauge threads directly into a matching ½-inch female NPT port. No electrical wiring or calibration is required because the instrument is purely mechanical. The bottom connection orientation means the dial faces upward when mounted on a horizontal pipe. The case carries no IP or NEMA rating, so the gauge should be shielded from wash-down or submersion.

Suits plant technicians monitoring hydraulic

Operators who need a local, easy-to-read indication of process pressure up to 160 psi will find the large dial and tight accuracy useful. Buyers who require remote transmission, data logging or alarm contacts should look at a transducer instead. The lack of vibration resistance and fillable option also makes this model a poor fit for high-pulsation machinery.

Questions about this item

How do I verify the gauge reads within the stated +/- 0.5 Percent accuracy after installation?

Apply a known reference pressure within the 0 to 160 psi range and compare the 4 1/2 in dial reading; the pointer should stay within half a percent of the true value.

What components come with the Ashcroft 451259SD04L160# gauge and what must be sourced separately?

The gauge includes the 4 1/2 in polybutylene terephthalate case, glass lens, and 1/2 in male NPT bottom connection; pipe fittings, thread sealant, and any calibration kit are not included.

Which pressure range version of the 451259 series should I select for a system that operates up to 160 psi?

Choose the 0 to 160 psi model so the normal operating pressure sits near mid-scale on the white dial for best readability and accuracy.
