Ashcroft 662876001439 Pressure Gauge 0-30 Psi 2.5in Dial

Product Description

The ASHCROFT 662876001439 is a commercial-grade analog pressure gauge designed for monitoring system pressure in a wide range of industrial and mechanical applications. It features a 2-1/2 inch dial, a measurement range of 0 to 30 psi, and a 1/4 inch NPT center back mount connection. The steel case provides durable protection in typical service environments, while the bronze Bourdon tube ensures reliable pressure response. Accuracy is rated at 3-2-3 percent of scale across the full range. Licensed plumbers, HVAC technicians, and mechanical contractors use this gauge as a standard instrument for pressure verification and system diagnostics.

This gauge is suited for residential and light commercial plumbing, HVAC, and fluid system applications where a compact, back-mount panel or pipe installation is required. The center back mount configuration allows direct inline or panel mounting, keeping the dial face forward and readable. The polycarbonate lens resists impact and provides a clear view of the analog dial under field conditions. It is commonly installed on boilers, water systems, compressed air lines, and similar low-to-moderate pressure circuits operating within the 0 to 30 psi range.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician in accordance with applicable local codes and IPC guidelines. Depressurize and isolate the system fully before removing or installing the gauge. Apply thread sealant tape or compound to the NPT threads and tighten to hand-tight plus a partial turn — do not overtighten, as this can crack the gauge port or distort the case. After installation, slowly restore system pressure and inspect for leaks before returning the system to service.
