Ashcroft 662876749746 Digital Vacuum Gauge 2.5in Npt

Product Description

The ASHCROFT 662876749746 is a digital pressure gauge designed to measure vacuum levels in the range of 30 to 0 inches Hg (VAC). It features a 2.5-inch digital dial housed in a black plastic case with stainless steel wetted parts and a polycarbonate lens. Accuracy is rated at 0.25% of scale, making it suitable for applications requiring precise low-pressure vacuum readings. The 1/4-inch NPT lower-mount connection keeps the gauge in line with standard process fittings. Licensed HVAC technicians, plumbers, and industrial service professionals install this gauge in process lines and service setups where vacuum measurement is required.

This gauge is suited for residential and light commercial applications where vacuum monitoring is part of routine service or system verification. The IP67 ingress-protection rating means it can withstand dust and temporary water immersion, making it appropriate for field service environments. It carries CE, CRN, UL 61010, and cUL certifications, which are commonly required in industrial and commercial installation contexts. The operating temperature range of -4 degrees F to 140 degrees F (-20 degrees C to 60 degrees C) covers most standard indoor and outdoor service conditions. It is part of the ASHCROFT DG25 series.

Compatibility

Designed as an OEM-style replacement or service gauge for systems requiring a 2.5-inch digital vacuum gauge with a 1/4-inch NPT lower-mount connection and stainless steel wetted parts.

Installation Notes

Installation should be performed by a licensed HVAC technician, plumber, or qualified service professional. Shut down and depressurize the system fully before removing or installing any pressure gauge. Apply thread sealant appropriate for the process fluid and verify that the 1/4-inch NPT threads are clean and undamaged before installation. Do not overtighten the fitting, as the plastic case and connection body have torque limitations inherent to their construction.
