Ashcroft 82117XLL Pressure Gauge 2.5 in 0-30 Psi Center Back

Product Description

The ASHCROFT 82117XLL is an analog pressure gauge built for accurate pressure monitoring in demanding industrial, commercial, and mechanical service environments. With a 2.5-inch dial face and a pressure range of 30 to 0 psi, this gauge delivers 1% of scale accuracy, making it appropriate for applications where reliable readings matter. The stainless steel case and stainless steel wetted parts provide corrosion resistance in wet or chemically aggressive service conditions. The center back mount configuration positions the gauge flush against panel surfaces or bulkhead installations. Licensed plumbers, HVAC technicians, and pipefitters are the primary installers of this type of instrumentation.

This gauge is suited for use in residential and light commercial plumbing systems, HVAC hydronic piping, compressed air lines, and process piping where a panel-mount or back-connect gauge is required. The 0.25-pound weight and compact 2.5-inch dial make it practical for tight equipment rooms and skid-mounted systems. The no-fill, dry-dial design means no silicone or glycerin fill is present, keeping it appropriate for environments where fluid contamination is a concern. The center back mount with 1/4-inch thread connects directly to standard NPT fittings common in U.S. trade installations.

Key Features

• 1% of scale accuracy for reliable field readings
• Stainless steel case and stainless steel wetted parts for corrosion resistance
• Center back mount with 1/4-inch NPT thread connection
• Dry, no-fill design — no liquid filler present
• Compact 2.5-inch dial diameter suitable for panel and bulkhead installations

Compatibility

Designed as an OEM-style replacement or new-install analog pressure gauge for residential and commercial plumbing, HVAC, and process piping systems using standard 1/4-inch NPT back-connect fittings.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Depressurize and isolate the line completely before removing or installing any pressure instrumentation. Use thread sealant tape or compound rated for the service fluid on the NPT connection — do not overtighten, as stainless gauge cases can crack at the socket. Verify the gauge pressure range is appropriate for the system operating pressure before placing the line back into service.
