Ashcroft 94889XLL Pressure Gauge 0-100 Psi 2.5 in Mnpt

Product Description

The ASHCROFT 94889XLL is an industrial pressure gauge designed for accurate pressure monitoring in a wide range of fluid and gas systems. It features a 2.5-inch analog dial with a 0 to 100 psi range and 1 percent of scale accuracy. The gauge is built with a 304/316 stainless steel case and 316 stainless steel wetted parts, making it well-suited for corrosive media and demanding environments. The center back mount configuration with a 1/4-inch MNPT connection allows straightforward panel or pipe installation. Licensed technicians and industrial service professionals across HVAC, plumbing, and process piping applications install this type of gauge as part of routine system instrumentation.

This gauge is used in residential and commercial applications where reliable pressure readings are required on water, steam, gas, or compatible fluid systems. The no-fill, dry bourdon tube design keeps the unit lightweight at 0.25 pounds and simplifies service. Its stainless steel construction suits installations where moisture, mild corrosives, or washdown conditions are present. The 1/4-inch MNPT center back connection fits standard gauge ports found on manifolds, pipe tees, and equipment panels across a broad range of trade applications.

Compatibility

Designed as an OEM-style or replacement industrial pressure gauge suitable for standard 1/4-inch MNPT gauge ports on pipe assemblies, manifolds, and equipment panels in HVAC, plumbing, and general process piping systems.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified industrial mechanic in accordance with applicable local codes and the system manufacturer's guidelines. Depressurize and isolate the system before removing or installing any pressure gauge. Apply thread sealant appropriate for the media being measured to the MNPT threads; do not overtighten, as stainless fittings are susceptible to galling. Verify the gauge pressure range is compatible with the system's normal and maximum operating pressures before placing the system back in service.
