Ashcroft 94891XLL Pressure Gauge 2.5in 0-200 Psi Center Back

Product Description

The ASHCROFT 94891XLL is an analog pressure gauge designed for industrial and mechanical system monitoring applications. Featuring a 2.5-inch dial with a 0 to 200 psi range, this gauge delivers 1% of scale accuracy, making it suitable for process lines, HVAC equipment, plumbing systems, and similar installations where reliable pressure readings are required. The stainless steel case and stainless steel wetted parts provide corrosion resistance in demanding environments. It mounts via a center back connection with a 1/4-inch thread. No liquid fill is used, keeping the design straightforward for general-purpose pressure monitoring.

This gauge is appropriate for residential and light commercial applications including hydronic heating systems, compressed air lines, water supply systems, and refrigeration equipment pressure ports. The center back mount configuration suits panel-mounted or manifold-mounted installations where the connection point and dial face need to align on the same axis. Licensed plumbers, HVAC technicians, and pipefitters commonly install this type of gauge during system commissioning or as a replacement for failed instrumentation.

Key Features

• 2.5-inch analog dial for clear on-site pressure readings
• 0 to 200 psi pressure range suitable for a wide range of mechanical systems
• 1% of scale accuracy for reliable measurement
• Stainless steel case and stainless steel wetted parts for corrosion resistance
• Center back mount with 1/4-inch thread for straightforward panel or manifold installation
• Non-liquid-filled design for general-purpose use

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for plumbing, HVAC, and light industrial process systems requiring a 1/4-inch center back mount connection and a 0 to 200 psi range.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Depressurize and isolate the system before removing an existing gauge or threading in a new one. Apply thread sealant or PTFE tape appropriate for the system fluid before threading the gauge into the port. Do not over-tighten the connection; use a wrench on the gauge fitting hex, not on the case body.
