Ashcroft 83155XLL Pressure Gauge 0-7500 Psi 3.5 in Dial

Product Description

The ASHCROFT 83155XLL is an analog pressure gauge built for industrial and mechanical applications requiring accurate high-pressure measurement up to 7500 psi. The gauge features a 3.5-inch dial with a 1/4-inch lower-mount connection, making it straightforward to install inline or at a port fitting. The stainless steel case and stainless steel wetted parts provide corrosion resistance in demanding service environments. Accuracy is rated at 1 percent of full scale, meeting standard requirements for process monitoring, hydraulic systems, and high-pressure plumbing circuits. This is a dry-fill (no liquid filler) gauge suitable for non-pulsating or low-vibration service conditions.

This gauge is used in commercial and industrial settings where high-pressure fluid or gas monitoring is required. Typical applications include hydraulic test stands, high-pressure water systems, compressor discharge lines, and process piping. The lower-mount configuration positions the connection at the 6 o'clock position on the gauge body, allowing direct panel or pipe installation. Plumbers, pipefitters, HVAC technicians, and industrial maintenance professionals are the primary installers.

Key Features

• Pressure range of 0 to 7500 psi for high-pressure system monitoring
• Stainless steel case and stainless steel wetted parts for corrosion resistance
• 3.5-inch analog dial for easy reading at distance
• 1/4-inch lower-mount connection for direct pipe or port installation
• 1 percent of full-scale accuracy for reliable process readings
• Dry-fill design suited to stable, low-vibration service conditions

Compatibility

Designed as a direct-mount replacement or new-installation pressure gauge for systems with a 1/4-inch NPT lower-mount port operating up to 7500 psi.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician. Depressurize and isolate the system completely before removing any existing gauge or fittings. Apply appropriate thread sealant to the 1/4-inch male threads per the applicable piping code — use PTFE tape or pipe dope rated for the service pressure and fluid type. Do not over-torque the gauge body; use the hex flats on the connection fitting, not the gauge case, to tighten.
