Ashcroft 662876752805 Digital Pressure Gauge 0-500 Psi

Product Description

The ASHCROFT 662876752805 is a digital pressure gauge designed for accurate pressure monitoring in industrial, HVAC, plumbing, and mechanical systems. It features a 2.5-inch dial with a digital readout, a pressure range of 0 to 500 psi, and an accuracy rating of 0.5% of full scale. The gauge uses a lower-mount, 1/4-inch NPT connection and houses stainless steel wetted parts inside a black plastic case with a polycarbonate lens. Licensed contractors and field technicians install this gauge on pipelines, equipment, and test assemblies where a clear digital readout and durable construction are required.

This gauge fits residential and light commercial applications where reliable pressure indication is needed on water, gas distribution, or HVAC systems. The lower-mount configuration positions the connection at the bottom of the gauge body, making it well-suited for panel-mount or pipe-mount installations where the process connection enters from below. It is not liquid-filled, keeping the unit lightweight and straightforward to install in non-vibration-intensive environments.

Key Features

• Digital display with 0.5% of scale accuracy for precise pressure readings
• 0 to 500 psi pressure range suitable for a wide variety of trade applications
• Stainless steel wetted parts resist corrosion from process media
• 1/4-inch lower-mount NPT connection for standard pipe fitting compatibility
• IP67-rated enclosure protects against dust ingress and temporary water immersion
• Certified to CE, CRN, UL 61010, and cUL standards

Compatibility

Part of the ASHCROFT DG25 series. Designed for use on systems with 1/4-inch NPT lower-mount connections where a 0 to 500 psi digital gauge is required. Verify process media compatibility with stainless steel wetted parts before installation.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or pipefitter following applicable IPC or IFGC guidelines. Shut off and depressurize the system completely before removing the existing gauge or installing this unit. Apply thread sealant appropriate for the process media to the NPT threads — do not over-tighten, as the plastic case can be damaged by excessive torque. Operating temperature limits of -4 degrees F to 140 degrees F must not be exceeded in service.
