Ashcroft 662876750069 Digital Pressure Gauge 0-300 Psi

Product Description

The ASHCROFT 662876750069 is a digital pressure gauge designed for accurate pressure measurement in trade and industrial service applications. It features a 2.5-inch dial with a digital readout, a 0 to 300 psi range, and a lower-mount 1/4-inch NPT connection. The plastic case houses stainless steel wetted parts, and the polycarbonate lens protects the display. Accuracy is rated at 0.25 percent of scale, making it suitable for applications that demand reliable, repeatable readings. It is not liquid filled. HVAC technicians, plumbers, and mechanical contractors commonly install this gauge for system pressure monitoring and diagnostics.

This gauge is suited for residential and light commercial applications where a compact, digital readout is preferred over analog. The lower-mount NPT connection allows direct installation into standard pipe fittings, manifolds, or test ports. The IP67-rated enclosure resists dust and water ingress, supporting use in field service environments. The operating temperature range of -4 degrees F to 140 degrees F covers most HVAC and plumbing service conditions. The Series DG25 platform is built for durability in routine service and installation work.

Key Features

• Digital readout with 0.25 percent of scale accuracy for reliable pressure readings
• 0 to 300 psi pressure range suitable for HVAC and plumbing system diagnostics
• Stainless steel wetted parts for corrosion resistance in wet service applications
• IP67-rated plastic case with polycarbonate lens for dust and water protection
• Lower-mount 1/4-inch NPT connection for direct pipe fitting installation
• CE, CRN, UL 61010, and cUL listed for broad compliance requirements

Compatibility

Designed as an OEM-style replacement or field-service gauge compatible with standard 1/4-inch NPT lower-mount pressure gauge ports in HVAC, plumbing, and mechanical systems.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor. Shut off system pressure and bleed down to zero psi before installing or removing the gauge. Apply thread sealant appropriate for the system media to the NPT threads before making up the connection. Do not exceed the rated maximum pressure or operating temperature range of the gauge.
