Ashcroft 662876000548 Pressure Gauge 0-100 Psi 2 in

Product Description

The ASHCROFT 662876000548 is a commercial-grade analog pressure gauge designed for general-purpose pressure monitoring in mechanical, HVAC, plumbing, and industrial service applications. It features a 2-inch dial with a 0 to 100 psi range and a 3-2-3 percent of scale accuracy rating, meaning readings are most accurate at mid-scale. The steel case and polycarbonate lens provide durable protection in typical service environments. The bronze Bourdon tube is the internal sensing element that deflects proportionally to applied pressure and drives the analog pointer. This gauge is installed by licensed plumbers, pipefitters, HVAC technicians, and mechanical contractors.

This gauge is suited for residential and light commercial systems where a compact 2-inch dial fits panel or pipe installations with limited space. The 1/4-inch NPT center back mount connection allows direct installation into threaded ports on manifolds, pressure vessels, pumps, or piping systems. Its CRN certification indicates compliance with Canadian Registration Number requirements, making it acceptable for use on pressure-containing equipment in Canadian jurisdictions as well as standard domestic trade applications.

Key Features

• 0 to 100 psi range with 3-2-3 percent of scale accuracy for reliable mid-range readings
• 2-inch analog dial for compact installations
• 1/4-inch NPT center back mount for direct threaded pipe or port connection
• Bronze Bourdon tube sensing element for compatibility with common system fluids
• Steel case with polycarbonate lens for durability in service environments
• CRN certified for use on pressure-containing equipment

Compatibility

Designed as a direct-fit commercial pressure gauge for any system with a 1/4-inch NPT threaded port requiring a 0 to 100 psi analog pressure gauge with center back mount.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Depressurize and isolate the system completely before removing an existing gauge or installing this unit. Apply thread sealant or PTFE tape to the NPT threads per standard trade practice, and do not overtighten, as cast or machined port bosses can crack. Verify the system operating pressure falls within the 0 to 100 psi range before commissioning.
