Ashcroft 662876100217 Pressure Gauge 0-300 Psi 2.5in Npt

Product Description

The ASHCROFT 662876100217 is a commercial-grade analog pressure gauge designed for industrial and mechanical system monitoring. It features a 2.5-inch steel case dial with a 0 to 300 psi range and reads through a polycarbonate lens for impact resistance. The bronze Bourdon tube provides reliable pressure sensing across the full measurement span. Accuracy is rated at 3-2-3 percent of scale, meaning the middle 40 percent of the range holds tighter tolerance than the outer zones. Connection is via a 1/4-inch NPT center back mount fitting, making it straightforward to install inline on pipe or manifold assemblies. Licensed plumbers, HVAC technicians, and mechanical contractors are the typical installers.

This gauge suits commercial and light industrial applications where consistent pressure monitoring is required on water, air, oil, or gas systems operating within the 0 to 300 psi range. The center back mount configuration is standard for panel-mount and manifold installations where the face of the gauge must remain flush or recessed. The NPT thread connection is compatible with standard North American pipe fittings across a wide range of plumbing, HVAC, and mechanical piping systems.

Key Features

• 0 to 300 psi pressure range with analog dial readout
• 3-2-3 percent of scale accuracy for reliable mid-range precision
• 2.5-inch diameter steel case for durability in field and panel applications
• Bronze Bourdon tube construction for broad fluid compatibility
• Polycarbonate lens resists impact and provides clear dial visibility
• 1/4-inch NPT center back mount for standard pipe and manifold connections
• CRN certified for use in Canadian pressure system applications

Compatibility

Designed as an OEM-style replacement or new-install commercial pressure gauge for plumbing, HVAC, and mechanical piping systems requiring a 1/4-inch NPT center back mount connection with a 0 to 300 psi range.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the system before removing or installing any pressure gauge. Apply thread sealant or PTFE tape to the NPT threads per the applicable plumbing or mechanical code, such as the IPC or IFGC. Do not over-tighten the fitting, as this can damage the Bourdon tube connection inside the gauge body.
