Ashcroft 662876752964 Digital Pressure Gauge 0-300 Psi

Product Description

The ASHCROFT 662876752964 is a digital pressure gauge designed for accurate pressure monitoring across a wide range of trade applications. It features a 2.5-inch dial, a measurement range of 0 to 300 psi, and a 0.5% of scale accuracy rating. The gauge uses a lower-mount, 1/4-inch NPT connection with stainless steel wetted parts, making it suitable for use with many common fluids and gases. The polycarbonate lens and black plastic case keep weight low at 0.42 pounds. HVAC technicians, plumbers, and mechanical contractors install this gauge where a clear digital readout and tight accuracy tolerance are required.

This gauge is appropriate for residential and light commercial applications involving pressurized systems such as HVAC refrigerant circuits, compressed air lines, water supply systems, and hydraulic test setups. The lower-mount NPT connection simplifies installation on standard threaded ports and manifolds. The DG25 series design supports use in environments where temperatures range from -4 degrees F to 140 degrees F, making it a practical fit for most indoor and moderate outdoor service conditions. The unit is not liquid-filled, which suits environments where a compact, lightweight digital readout is preferred over an analog dial.

Key Features

• Digital display with 0.5% of scale accuracy for precise pressure readings
• 0 to 300 psi range suits a broad set of HVAC, plumbing, and mechanical applications
• Stainless steel wetted parts resist corrosion in contact with measured media
• Lower-mount 1/4-inch NPT connection for standard threaded port installation
• IP67 rating provides protection against dust ingress and temporary water immersion
• CE, CRN, UL 61010, and cUL certifications support use in regulated installations

Compatibility

Designed as an OEM-style replacement or direct-install digital pressure gauge for systems with standard 1/4-inch NPT lower-mount pressure ports operating within a 0 to 300 psi range.

Installation Notes

This gauge is typically installed by licensed HVAC technicians, plumbers, or mechanical contractors working on pressurized systems. Always depressurize and isolate the system before removing an existing gauge or installing a new one. Apply thread sealant or PTFE tape to the NPT threads per standard practice, and do not overtighten the fitting, as the plastic case can crack under excessive torque. Verify that system operating pressure and media compatibility fall within the gauge specifications before placing into service.
