Ashcroft 95085 Pressure Gauge 2.5 in Dial Npt Lower Mount

Product Description

The ASHCROFT 95085 is a compound vacuum-pressure gauge designed for applications requiring measurement across both positive and negative pressure ranges. It features a 2.5-inch analog dial with a range of -30 to 30 inches of mercury (in Hg), a 1/4-inch NPT lower-mount connection, and a stainless steel case. Accuracy is rated at 1 percent of full scale, meeting standard industrial requirements. The dry (non-liquid-filled) construction suits general-purpose use in HVAC, refrigeration, plumbing, and light industrial systems. Licensed HVAC technicians and plumbers are the primary installers for this type of instrument.

This gauge is suited for residential and light commercial installations where monitoring of vacuum or low-pressure conditions is required. Typical applications include suction-side refrigerant line monitoring, vacuum system verification, and low-pressure gas or fluid system checks. The lower-mount NPT connection allows direct panel or pipe installation with the dial face oriented upward for easy reading. The stainless steel case provides corrosion resistance in moderately harsh service environments.

Key Features

• Compound range: -30 to 30 in Hg, covering both vacuum and positive pressure in a single instrument
• 2.5-inch analog dial for clear field readability
• 1/4-inch NPT lower-mount connection for direct pipe or panel installation
• Stainless steel case for corrosion resistance in damp or chemical-adjacent environments
• 1 percent of scale accuracy meets standard industrial and HVAC measurement requirements
• Dry (non-liquid-filled) construction suitable for general-purpose service

Compatibility

Designed as an OEM-style replacement or direct-install gauge for residential and light commercial HVAC, refrigeration, plumbing, and industrial systems requiring a 1/4-inch NPT lower-mount compound vacuum-pressure gauge with a 2.5-inch dial.

Installation Notes

Installation is performed by a licensed HVAC technician or plumber. Depressurize and isolate the system fully before removing any existing gauge or fitting. Apply appropriate thread sealant to the NPT connection per IPC and IFGC guidelines; do not over-tighten, as stainless steel gauge housings can crack if forced. Verify the pressure range of the system does not exceed the gauge rating before placing the system back in service.
