Low Pressure Gauge 0 to 3 psi

This ZORO SELECT gauge measures low pressure from 0 to 3 psi with a 2 1/2 inch dial. It uses a copper alloy diaphragm sensor and a 1/4 inch male NPT bottom connection. The steel case and polycarbonate lens suit industrial test and measurement tasks. Accuracy is rated at +/- 1.5 percent.

Upgrade from uncalibrated or damaged gauges

Replace gauges that have lost calibration or show physical damage to the sensor or lens. The jump is worth it when readings must stay within the stated accuracy for safety or process control. It does not serve applications needing IP or NEMA rated enclosures or hazardous location approvals.

Simple threaded installation

Thread the 1/4 inch NPT male connection directly into the process port. No panel mounting hardware is included or supported. The main issue is cross-threading the copper alloy socket during tightening. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

What thread size does the 1/4 in NPT connection require for mounting?

The gauge uses a 1/4 in male NPT thread that screws into a matching female NPT port.

How do you install the diaphragm sensor without damaging the copper alloy socket?

Apply thread sealant to the NPT threads, then tighten with a wrench on the socket flats only — never on the case.

When should the gauge be replaced if the +/- 1.5 percent accuracy drifts?

Replace it when readings fall outside the stated tolerance or if the polycarbonate lens becomes cracked or clouded.
