Ashcroft 662876749919 Digital Pressure Gauge 0-200 Psi

Product Description

The ASHCROFT 662876749919 is a digital pressure gauge designed for accurate pressure monitoring in HVAC, plumbing, and industrial fluid systems. It features a 2.5-inch dial with a digital readout, a measurement range of 0 to 200 psi, and an accuracy rating of 0.25 percent of scale. The black plastic case houses stainless steel wetted parts, making it suitable for use with a wide range of media. The lower-mount 1/4-inch NPT connection allows for direct inline installation. Licensed contractors and service technicians install this gauge to verify system pressures during commissioning, maintenance, and troubleshooting.

The DG25 series gauge is suited for residential and light commercial HVAC systems, hydronic heating and cooling circuits, compressed air lines, and plumbing pressure testing. The IP67 rating means it can withstand temporary water immersion, making it viable in wet or outdoor service environments. The lower-mount NPT connection fits standard gauge ports found on manifolds, tee fittings, and pressure test ports. Operating temperature range is -4 degrees F to 140 degrees F, covering typical mechanical room and outdoor conditions.

Key Features

• Digital readout with 0.25 percent of scale accuracy for precise pressure readings
• Stainless steel wetted parts resist corrosion across a broad range of fluid types
• IP67-rated enclosure withstands dust ingress and temporary water immersion
• Polycarbonate lens protects the display in demanding field conditions
• Lower-mount 1/4-inch NPT connection for direct inline installation
• Certified to CE, CRN, UL 61010, and cUL standards

Compatibility

Designed as a direct-fit replacement or new-installation digital pressure gauge for systems using 1/4-inch NPT lower-mount gauge ports in the 0 to 200 psi operating range.

Installation Notes

Installation is typically performed by a licensed HVAC technician, plumber, or pipefitter. Isolate and depressurize the system completely before installing or removing the gauge. Apply thread sealant tape or pipe dope to the NPT threads per standard plumbing practice and applicable IPC or IFGC code requirements. Do not overtighten the connection; hand-tight plus wrench-snugged is sufficient for NPT gauge ports to avoid cracking the plastic case.
