Ashcroft 662876000333 Pressure Gauge 160 Psi 1.5 in Npt

Product Description

The ASHCROFT 662876000333 is a compact analog pressure gauge designed for monitoring system pressure in plumbing, HVAC, and light industrial applications. It features a 1.5 inch dial with a 0 to 160 psi range and connects via a 1/8 inch NPT center back mount fitting. The ABS (acrylonitrile butadiene styrene) case keeps the gauge lightweight at 0.3 pounds, making it well-suited for tight spaces where a full-size gauge is impractical. Licensed plumbers, HVAC technicians, and pipefitters typically install this gauge during system commissioning or pressure testing.

This gauge fits center back mount installations where a 1/8 inch NPT port is present. Its 0 to 160 psi range covers common residential and light commercial water, air, and fluid service applications. The analog dial provides a direct, at-a-glance pressure reading without requiring electronics or a power source. It is a practical choice for boiler systems, compressed air lines, water supply monitoring, and similar low-to-medium pressure circuits.

Key Features

• 0 to 160 psi analog pressure range for residential and light commercial service
• 1.5 inch dial diameter for compact installation in confined spaces
• 1/8 inch NPT center back mount connection for direct panel or pipe installation
• ABS case construction — lightweight and corrosion-resistant in dry environments
• No external power required — passive analog readout

Compatibility

Designed as an OEM-style replacement or add-on gauge for residential and light commercial plumbing, HVAC, and compressed air systems requiring a 1/8 inch NPT center back mount pressure gauge with a 1.5 inch dial.

Installation Notes

This gauge is installed by licensed plumbers or HVAC technicians. Depressurize and isolate the system before removing an existing gauge or threading this unit into service. Apply thread sealant tape or paste rated for the system fluid to the NPT threads before installation — do not overtighten, as ABS cases can crack under excessive wrench torque. Verify the system operating pressure does not exceed 160 psi before placing the gauge in service.
