Ashcroft 94480 Pressure Gauge 0-400 Psi 2.5 in Dial Npt

Product Description

The ASHCROFT 94480 is a liquid-filled industrial pressure gauge designed for accurate pressure monitoring in demanding service environments. It features a 2.5-inch analog dial with a 0 to 400 psi range and delivers 1 percent of scale accuracy. The case is constructed from grade 304/316 stainless steel, and the Bourdon tube is 316 stainless steel, making this gauge well suited for corrosive or wet service conditions. The lower-mount, 1/4-inch NPT connection allows direct inline installation on pipes, manifolds, and process equipment. Licensed HVAC technicians, plumbers, and industrial service professionals install this type of gauge on pressurized systems requiring continuous pressure indication.

This gauge is appropriate for a wide range of commercial and industrial applications including HVAC refrigerant circuits, compressed air systems, hydraulic lines, water treatment systems, and general process piping. The liquid-filled design dampens needle vibration and protects internal components in high-pulsation or vibration-prone environments. The polycarbonate lens provides impact resistance and clear readability in field conditions. It is part of the ASHCROFT 1009 Series, which is built to industrial service standards.

Key Features

Compatibility

Designed as an OEM-style industrial pressure gauge for use on pressurized piping systems, HVAC equipment, compressed air lines, and process equipment requiring a 1/4-inch NPT lower-mount connection and a 0 to 400 psi range.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified industrial service professional. Depressurize and isolate the system completely before removing any existing gauge or installing this unit. Apply thread sealant appropriate for the service media to the NPT threads and tighten to hand-tight plus the number of turns required to achieve a leak-free seal without overtightening the stainless steel fitting. Verify the system pressure range does not exceed the 400 psi maximum rating before returning the system to service.
