Ashcroft 662876749788 Pressure Gauge 2.5 in 0-100 Psi Npt

Product Description

The ASHCROFT 662876749788 is a lower-mount pressure gauge designed for trade and industrial service applications requiring reliable pressure readings up to 100 psi. The gauge features a 2.5-inch dial housed in a black plastic case with stainless steel wetted parts, making it well suited for systems where corrosion resistance at the process connection matters. Accuracy is rated at 0.25 percent of scale, which meets the demands of most HVAC, plumbing, and light industrial monitoring tasks. The 1/4-inch NPT lower-mount connection allows straightforward inline or manifold installation. This gauge is not liquid-filled, keeping weight low at 0.42 pounds.

This gauge is used in residential and commercial settings where a compact, direct-reading pressure instrument is needed on water, air, or gas distribution lines. The lower-mount NPT connection is standard across a wide range of pipe fittings and manifold blocks, making it a common replacement or add-on gauge for HVAC technicians, plumbers, and pipefitters working on pressure monitoring points in mechanical systems. The 2.5-inch dial size provides a readable display in tight equipment spaces.

Key Features

• 0 to 100 psi pressure range for common HVAC and plumbing monitoring applications
• 0.25 percent of scale accuracy for reliable readings
• 2.5-inch dial diameter for clear visibility in confined spaces
• Stainless steel wetted parts resist corrosion at the process connection
• 1/4-inch NPT lower-mount connection for standard pipe and manifold fitment
• Lightweight plastic case at 0.42 pounds reduces installation load

Compatibility

Designed as a standard-replacement lower-mount pressure gauge for systems using 1/4-inch NPT connections in residential and commercial HVAC, plumbing, and light industrial piping applications.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or pipefitter. Isolate and depressurize the line fully before removing any existing gauge or fitting. Apply thread sealant tape or compound to the NPT threads per the applicable IPC or IFGC guidelines before seating the gauge. Do not over-tighten the plastic case body; use a wrench only on the hex fitting at the connection base.
