Ashcroft 82108XLL Pressure Gauge 2.5 in 0-300 Psi Center Back

Product Description

The ASHCROFT 82108XLL is an analog pressure gauge designed for accurate pressure monitoring in plumbing, HVAC, and industrial fluid systems. It features a 2.5-inch dial face with a 0 to 300 psi range and delivers 1% of scale accuracy, making it suitable for applications where reliable pressure readings are critical. The stainless steel case and stainless steel wetted parts provide corrosion resistance in demanding service environments. This gauge mounts via a 1/4-inch center back connection and is a dry (no-fill) instrument. It is installed by licensed plumbers, HVAC technicians, and pipefitters in both residential and commercial settings.

The 82108XLL is suited for use in water supply systems, hydronic heating loops, compressed air lines, and other fluid or gas service applications where pressures fall within the 0 to 300 psi range. Its center back mount configuration positions the gauge flush against a panel or pipe fitting, making it a common choice for equipment panels and manifold assemblies. The stainless steel construction handles moderate chemical exposure and wet environments without significant degradation.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off and depressurize the system completely before removing any existing gauge or fitting. Apply appropriate thread sealant tape to the 1/4-inch NPT threads before installation and hand-tighten before using a wrench to avoid overtightening the gauge body. Follow local plumbing codes and applicable IPC or IFGC guidelines for gauge placement and service access.
