Ashcroft 251009S02LXLL4K Pressure Gauge 0-4000 Psi

Product Description

The ASHCROFT 251009S02LXLL4K is an analog pressure gauge built for demanding industrial and mechanical service. It features a 2.5-inch dial with a 0 to 4000 psi range, a stainless steel case, and stainless steel wetted parts for corrosion resistance in harsh fluid environments. The lower-mount, 0.25-inch threaded connection allows direct inline installation on piping or equipment. Accuracy is rated at 1 percent of scale, making it suitable for process monitoring applications where reliable, repeatable readings are required. HVAC technicians, plumbers, pipefitters, and industrial maintenance personnel are the primary installers of this gauge type.

This gauge is appropriate for residential and commercial applications involving high-pressure systems such as hydraulic lines, compressed air systems, water pressure monitoring, and process piping. The dry, no-fill design keeps the instrument lightweight and maintenance-free in static or low-vibration installations. The stainless steel wetted parts make it compatible with water, many oils, and mildly corrosive media where brass or steel wetted parts would be unsuitable.

Key Features

• 0 to 4000 psi pressure range for high-pressure system monitoring
• Stainless steel case and stainless steel wetted parts for corrosion resistance
• 2.5-inch analog dial for clear, direct reading at close range
• Lower-mount, 0.25-inch threaded connection for straight inline installation
• 1 percent of scale accuracy for reliable process readings
• Dry, no-fill design requires no liquid maintenance

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for high-pressure piping, hydraulic, compressed air, and process systems requiring a 0.25-inch lower-mount threaded connection and a 2.5-inch dial format.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician. Isolate and depressurize the system completely before removing or installing any pressure gauge. Apply appropriate thread sealant to the male threads per the system fluid compatibility requirements. Do not overtighten the threaded connection, as this can damage the gauge socket or fitting.
