Ashcroft 94893XLL Pressure Gauge 2.5 in 0-400 Psi Center Back

Product Description

The ASHCROFT 94893XLL is an analog pressure gauge designed for accurate pressure measurement in mechanical, HVAC, plumbing, and industrial service applications. It features a 2.5-inch dial with a 0 to 400 psi pressure range and delivers 1% of scale accuracy, making it suitable for demanding field and shop installations. The gauge is built with a stainless steel case and stainless steel wetted parts, providing corrosion resistance in wet or chemically active environments. It is non-liquid-filled and mounts via a 1/4-inch center back connection. Licensed trades and mechanical contractors are the primary installers.

This gauge is well suited for residential and light commercial systems where a compact, durable pressure-reading instrument is needed at pumps, compressors, boilers, and piping manifolds. The center back mount configuration integrates cleanly into panel or inline installations where the gauge face must be flush and readable from the front. The stainless steel construction makes it appropriate for use in refrigeration, potable water, steam, or corrosive-fluid piping, subject to media compatibility verification at the point of application.

Key Features

• 2.5-inch analog dial for clear, at-a-glance pressure readings
• 0 to 400 psi pressure range covers a broad range of mechanical system applications
• 1% of scale accuracy for reliable field measurement
• Stainless steel case and stainless steel wetted parts for corrosion resistance
• 1/4-inch center back mount for clean panel or inline installation
• Non-liquid-filled design simplifies handling and installation in variable-temperature environments

Compatibility

Designed as a direct-fit analog pressure gauge for systems requiring a 1/4-inch center back mount connection with a 2.5-inch dial format. Verify thread type and pressure range against the target system before installation.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor in accordance with applicable local codes and the system manufacturer's service guidelines. Isolate and depressurize the system fully before removing any existing gauge or fitting. Apply thread sealant appropriate for the service media to the male threads; do not over-tighten, as this can crack the gauge socket. After installation, pressurize slowly and inspect for leaks before returning the system to normal operation.
