Ashcroft 662876000159 Pressure Gauge 0-100 Psi 1.5in

Product Description

The ASHCROFT 662876000159 is a commercial-grade analog pressure gauge designed for monitoring system pressure in a wide range of mechanical and process applications. It features a 1.5-inch dial with a 0 to 100 psi range and a center back mount configuration. The 1/8-inch NPT threaded connection makes it compatible with standard fittings found in HVAC, plumbing, and light industrial systems. Accuracy is rated at 3-2-3 percent of scale across the full range. The Bourdon tube is bronze construction, and the case is steel with a polycarbonate lens. Licensed HVAC technicians, plumbers, and pipefitters typically install this gauge as part of a pressure monitoring or diagnostic assembly.

This gauge is suited for residential and light commercial applications where a compact, readable pressure indicator is needed. Common install scenarios include boiler systems, compressed air lines, water supply lines, pump discharge monitoring, and HVAC refrigerant-adjacent pressure circuits. Its center back mount orientation makes it well-suited for panel or manifold installations where a flush, straight-back profile is required. The 1.5-inch dial size is appropriate for close-range reading in tight mechanical spaces.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-install commercial pressure gauge for systems with a 1/8-inch NPT center back port and a 0 to 100 psi service range.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or HVAC technician in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Shut off system pressure and bleed down to zero before removing any existing gauge or installing this unit. Apply appropriate thread sealant to the NPT threads and tighten to snug fit by hand before using a wrench — do not overtighten the brass port on the gauge body. Verify that the system operating pressure does not exceed the full-scale range of the gauge during normal or surge conditions.
