Ashcroft 94233XLL Pressure Gauge 0-3000 Psi 2.5in Dial

Product Description

The ASHCROFT 94233XLL is an industrial pressure gauge designed for accurate pressure monitoring in demanding commercial and industrial applications. It features a 2.5-inch analog dial with a 0 to 3000 psi range and delivers 1% of scale accuracy. The gauge uses a 316 stainless steel Bourdon tube paired with a 304/316 stainless steel case and stainless steel wetted parts, making it well suited for corrosive media and harsh service environments. The polycarbonate lens and no-fill construction keep the unit lightweight and straightforward to service. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers on process piping, refrigeration, and hydraulic systems.

The 94233XLL is appropriate for both residential and commercial installations wherever a reliable, corrosion-resistant pressure gauge is required. Its lower-mount MNPT 1/4-inch connection suits standard instrumentation ports on compressors, pumps, pressure vessels, boilers, and industrial process lines. The dry, no-fill design avoids liquid contamination concerns and simplifies installation in temperature-variable environments. This gauge meets a broad range of regulatory and certification standards, making it a practical choice for facilities subject to CRN, PED, or NEMA 4 enclosure requirements.

Key Features

• 0 to 3000 psi measurement range with 1% of scale accuracy
• 316 stainless steel Bourdon tube for corrosion resistance in aggressive media
• 304/316 stainless steel case and stainless steel wetted parts throughout
• 2.5-inch analog dial with polycarbonate lens for clear, easy reading
• Lower-mount MNPT 1/4-inch connection for standard instrumentation ports
• Dry no-fill construction — no silicone or glycerin fill to manage or replace
• Certified to CRN, IP54, IP65/NEMA 4, PED, and RoHS standards

Compatibility

Designed as an OEM-style replacement or new-install industrial pressure gauge for systems requiring a lower-mount, 1/4-inch MNPT connection with a 0 to 3000 psi range and a 2.5-inch dial format.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Isolate and fully depressurize the system before removing any existing gauge or fitting the new gauge into the port. Apply an appropriate thread sealant to the MNPT threads and hand-tighten before using a wrench on the hex flats — never apply torque to the gauge case or dial. Verify the system pressure range does not exceed the gauge maximum before returning the system to service.
