Ashcroft 662876131754 Pressure Gauge 0-400 Psi 2-1/2 in

Product Description

The ASHCROFT 662876131754 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 face with a 0 to 400 psi range and 3-2-3 percent of scale accuracy, making it suitable for applications where reliable pressure readings are critical. The steel case houses a bronze Bourdon tube sensing element, and the polycarbonate lens protects the dial face from environmental exposure. This gauge installs via a 1/4 inch NPT center back mount connection, a standard configuration commonly found in piping systems, compressed air lines, and fluid circuits. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers for this type of instrument.

This gauge is well suited for commercial and light industrial use where a durable, analog pressure-indicating instrument is required. The center back mount orientation allows direct panel or manifold installation in tight spaces where side or bottom connections are not practical. The 0 to 400 psi range covers a broad spectrum of applications including compressed air systems, hydraulic circuits, water supply lines, and process piping. The CRN certification indicates the gauge meets Canadian Registration Number requirements, broadening its usability in Canadian jurisdictions alongside standard US applications.

• 1/4 inch NPT center back mount for direct piping or panel installation
• Bronze Bourdon tube sensing element for reliable mechanical response
• Steel case construction for durability in commercial environments
• Polycarbonate lens protects dial face from impact and moisture
• CRN certified for use in applicable Canadian jurisdictions

Compatibility

Designed as an OEM-style replacement or new-installation commercial pressure gauge for systems using 1/4 inch NPT center back mount connections with a pressure range up to 400 psi.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes and the IFGC or IPC as relevant to the system type. Depressurize and isolate the system completely before removing any existing gauge or fitting the new one. Apply appropriate thread sealant to the NPT threads per the sealant manufacturer instructions, and do not overtighten the connection, as damage to the Bourdon tube or case can result. Verify the pressure range of the gauge is appropriate for the system before placing it in service.
