Ashcroft 95428XLL Vacuum Pressure Gauge 2.5 in Dial

Product Description

The ASHCROFT 95428XLL is a dry-type vacuum pressure gauge designed for applications requiring accurate negative-pressure monitoring from -30 inches Hg to 0 inches Hg. The gauge features a 2.5-inch analog dial with 1 percent of scale accuracy, making it suitable for precision service work in HVAC, plumbing, and industrial fluid systems. The stainless steel case provides corrosion resistance in harsh environments, while bronze wetted parts offer reliable compatibility with common system media. It mounts via a 0.25-inch center back connection and requires no liquid fill for standard operation. Licensed technicians and service pros install this gauge where a compact, readable vacuum indicator is needed at a panel or inline measurement point.

This gauge is suited for residential and commercial HVAC vacuum and refrigeration system monitoring, plumbing low-pressure measurement, and general industrial service where a dry analog vacuum gauge is specified. The center back mount configuration allows flush panel or manifold installation, keeping the dial face visible and the connection protected. The -30 to 0 inches Hg range covers full vacuum measurement typical of evacuation and suction-line diagnostics.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or instrumentation professionals. Isolate and depressurize the system completely before removing or installing any pressure gauge. Ensure thread sealant or PTFE tape is applied to male threads per standard trade practice, and do not overtighten the connection into bronze or brass fittings. Verify the gauge range is appropriate for the system being monitored before placing into service.
