Ashcroft 662876749805 Pressure Gauge 1000 Psi 2.5 in Dial

Product Description

The ASHCROFT 662876749805 is a lower-mount pressure gauge designed for monitoring system pressure in HVAC, plumbing, and industrial fluid-handling applications. It features a 2.5-inch dial with a 0 to 1000 PSI range and delivers 0.25 percent of scale accuracy, making it suitable for applications where reliable pressure readings are critical. The plastic case keeps the unit lightweight at 0.42 pounds, while stainless steel wetted parts resist corrosion from the media being measured. Connection is via a 1/4-inch NPT lower-mount fitting, which integrates directly into standard threaded ports. The gauge is non-liquid-filled and uses a black dial face for clear readability.

This gauge is suited for residential and light commercial HVAC systems, hydronic heating loops, compressed air lines, water supply lines, and similar fluid or gas service applications. The lower-mount NPT configuration allows direct in-line installation on manifolds, tees, and equipment ports commonly found in mechanical rooms and equipment installations. HVAC technicians, plumbers, and pipefitters are the primary trades that install and service this gauge type.

Key Features

• 0 to 1000 PSI pressure range for high-pressure monitoring applications
• 0.25 percent of scale accuracy for reliable, repeatable readings
• 2.5-inch dial diameter for visibility in tight installation spaces
• Stainless steel wetted parts resist corrosion from measured media
• 1/4-inch NPT lower-mount connection fits standard threaded ports
• Lightweight plastic case at 0.42 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for systems with standard 1/4-inch NPT lower-mount gauge ports in HVAC, plumbing, and fluid-handling applications.

Installation Notes

Installation is typically performed by a licensed HVAC technician, plumber, or pipefitter. Always isolate and depressurize the system before removing or installing any pressure gauge. Apply thread sealant or PTFE tape to the NPT threads per IPC and IFGC guidelines for the service fluid involved. Do not overtighten the gauge body; use only the wrench flats on the fitting hex to avoid damaging the case or dial.
