Ashcroft 83256XLL Pressure Gauge 3.5in 0-10000 Psi Center Back

Product Description

The ASHCROFT 83256XLL is an analog pressure gauge built for high-pressure monitoring applications in industrial, HVAC, plumbing, and process systems. The gauge features a 3.5-inch dial with a measurement range of 0 to 10000 psi and delivers 1% of scale accuracy, making it suitable for demanding service environments where reliable readings matter. The stainless steel case and stainless steel wetted parts provide corrosion resistance in harsh or wet conditions. It mounts via a center back connection with a 1/4-inch thread and ships as a dry, no-fill gauge. Licensed technicians and journeymen installers working on high-pressure systems are the primary installers of this gauge.

This gauge is appropriate for residential and commercial applications where high-pressure monitoring is required. Typical installation scenarios include hydraulic systems, compressed air lines, boiler systems, process piping, and high-pressure water systems. The dry, no-fill design is suited for environments where glycerin or silicone fill is not needed or not permitted. The center back mount configuration fits standard back-mount panel and pipe installations where a flush-face or in-line reading position is required.

Key Features

• High-range 0 to 10000 psi measurement capacity for demanding pressure applications
• 1% of scale accuracy for consistent and reliable pressure readings
• Stainless steel case and stainless steel wetted parts for corrosion resistance
• 3.5-inch analog dial for clear, easy-to-read pressure indication
• Center back mount with 1/4-inch thread for standard panel and pipe installations
• Dry, no-fill design eliminates concerns about fluid contamination or temperature expansion

Compatibility

Designed as an OEM-style replacement or direct-install analog pressure gauge for high-pressure piping, hydraulic, and process systems requiring a 3.5-inch center back mount gauge with a 1/4-inch thread connection.

Installation Notes

Installation of this pressure gauge should be performed by a licensed plumber, pipefitter, or qualified mechanical technician familiar with high-pressure systems and applicable codes such as the IPC or ASME B40.100. Depressurize and isolate the system completely before removing any existing gauge or fitting. Apply appropriate thread sealant to the 1/4-inch male threads per the sealant manufacturer instructions, and do not overtighten, as stainless fittings are susceptible to galling. After installation, bring system pressure up gradually and inspect for leaks before returning the system to full operation.
