Ashcroft 95091 Pressure Gauge 0-30 Psi 2.5 in Dial Npt

Product Description

The ASHCROFT 95091 is a liquid-filled industrial pressure gauge designed for analog pressure measurement in demanding process and mechanical applications. It features a 2.5-inch dial with a 0 to 30 psi range and delivers 1% of scale accuracy. The case is constructed from 304/316 stainless steel, the Bourdon tube is 316 stainless steel, and the lens is polycarbonate. The liquid fill reduces pointer vibration and dampens pulsation, extending service life in high-cycle systems. Licensed HVAC technicians, plumbers, pipefitters, and industrial maintenance professionals typically install this gauge in refrigeration, plumbing, compressed air, and general process piping systems.

The 95091 is suited for residential and commercial applications where a compact, corrosion-resistant pressure gauge is required. Lower mount configuration and 1/4-inch NPT male connection make it compatible with standard pipe fittings used in hydronic heating, water supply, pneumatic systems, and light process lines. The stainless steel construction makes it appropriate for mildly corrosive media where a standard carbon steel gauge would be inadequate. The liquid-filled design is particularly useful in environments with vibration or pressure pulsation.

Key Features

• 0 to 30 psi analog pressure range with 1% of scale accuracy
• 2.5-inch dial diameter for clear reading at close range
• Liquid-filled design dampens vibration and pressure pulsation
• 304/316 stainless steel case for corrosion resistance
• 316 stainless steel Bourdon tube for contact with process media
• Polycarbonate lens for impact resistance
• Lower mount with 1/4-inch NPT connection for standard pipe fitting compatibility

Compatibility

Designed as an OEM-style or replacement industrial pressure gauge for use with 1/4-inch NPT lower-mount fittings in plumbing, HVAC, compressed air, and light process piping systems.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified mechanical technician in accordance with applicable local codes and system requirements. Shut off and depressurize the system completely before removing or installing any pressure gauge. Apply thread sealant or PTFE tape to the NPT threads before installation and tighten to fitting snug — do not overtighten stainless fittings. Verify the gauge pressure range is appropriate for the system before placing it into service.
