Ashcroft 662876001477 Pressure Gauge 0-200 Psi 2.5 in Dial

Product Description

The ASHCROFT 662876001477 is a commercial-grade analog pressure gauge designed for use in plumbing, HVAC, and industrial fluid systems where reliable pressure monitoring is essential. It features a 2-1/2 inch dial with a 0 to 200 psi range and a 3-2-3 percent of scale accuracy class, making it suitable for general service applications where a verified pressure reading is required. The steel case provides durable protection in mechanical rooms and equipment rooms. The bronze Bourdon tube is the sensing element that translates system pressure into dial movement. Installation is handled by licensed plumbers, HVAC technicians, and mechanical contractors.

This gauge is suited for commercial pressure monitoring applications including hydronic heating systems, compressed air lines, water supply systems, and process piping. The 1/4 inch NPT center back mount configuration allows direct installation into a tapped fitting or manifold on the back of the gauge, keeping the dial face clean and readable. The polycarbonate lens protects the dial face from moisture and minor impact in typical mechanical service environments. It is sold individually and is appropriate for both new installation and replacement service.

Compatibility

Designed as an OEM-style replacement or new-installation commercial pressure gauge for plumbing, HVAC, and mechanical piping systems that accept a 1/4 inch NPT center back mount gauge connection.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off and depressurize the system fully before removing an existing gauge or threading in a new one. Use thread sealant tape rated for the system fluid and pressure range on the NPT threads. Do not use the dial body as a wrench surface — apply torque only to the hex fitting at the process connection.
