Ashcroft 94235XLL Pressure Gauge 0-6000 Psi 2.5 in Dial

Product Description

The ASHCROFT 94235XLL is an industrial-grade analog pressure gauge designed for accurate pressure measurement in demanding service applications. It features a 2.5-inch dial with a range of 0 to 6000 psi and delivers 1% of scale accuracy. The case and wetted parts are stainless steel, making this gauge suitable for corrosive media and harsh environments. The lower-mount, 1/4-inch MNPT connection allows direct inline installation on pipes, manifolds, and process equipment. No liquid fill is used, keeping the design straightforward for dry-service installations. Licensed HVAC technicians, plumbers, pipefitters, and industrial service techs are the primary installers for this type of gauge.

This gauge is suited for residential and commercial service applications where high-pressure measurement is required, including hydraulic systems, compressed gas lines, water treatment equipment, refrigeration service manifolds, and industrial process piping. The stainless steel construction supports use with a wide range of media including water, oils, gases, and mildly corrosive fluids. The lower-mount orientation is standard for panel, pipe saddle, and direct-process connections where the gauge mounts vertically above the tapping point.

Key Features

• 0 to 6000 psi range with 1% of scale accuracy for reliable high-pressure readings
• 316 stainless steel Bourdon tube for corrosion resistance in aggressive media
• 304/316 stainless steel case for durable, long-service-life performance in wet or outdoor environments
• Stainless steel wetted parts throughout minimize contamination risk
• Polycarbonate lens provides impact resistance and clear dial visibility
• Lower-mount 1/4-inch MNPT connection for straightforward inline installation
• Meets CRN, IP54, IP65/NEMA 4, PED, and RoHS standards

Compatibility

Designed as an OEM-style replacement or new-installation industrial pressure gauge for systems requiring a 1/4-inch MNPT lower-mount connection and a 0 to 6000 psi measurement range in dry-service configurations.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or qualified HVAC or industrial service technician. Depressurize and isolate the system completely before removing an existing gauge or making a new tapping connection. Apply thread sealant or PTFE tape to the MNPT threads per the applicable installation standard and tighten to the fitting manufacturer's recommended practice — do not over-torque the gauge body. Verify the system pressure range does not exceed the gauge maximum rating of 6000 psi before returning the line to service.
