Ashcroft 94330XLL Pressure Gauge 0-200 Psi 2.5in Dial Mnpt

Product Description

The ASHCROFT 94330XLL is an industrial-grade analog pressure gauge designed for accurate pressure measurement in demanding process and mechanical applications. It features a 2.5-inch diameter dial with a 0 to 200 psi range and delivers 1% of scale accuracy using a 316 stainless steel Bourdon tube. The stainless steel case and stainless steel wetted parts make it well suited for corrosive or hygiene-sensitive environments. A lower-mount MNPT connection simplifies installation on pipe lines and process equipment. This gauge is a dry (no-fill) unit, making it easy to handle and read in standard industrial environments. Licensed mechanical contractors and process technicians are the typical installers.

The 94330XLL is intended for industrial pressure monitoring across a wide range of applications including HVAC systems, plumbing lines, chemical process equipment, and general mechanical systems where reliable pressure indication is required. Its stainless steel wetted parts make it appropriate for use with mildly corrosive media and water-based systems. The lower-mount 0.25-inch MNPT connection allows direct installation into standard pipe fittings or manifold ports. The polycarbonate lens provides impact resistance and clear dial visibility in typical plant and field environments.

Key Features

• 0 to 200 psi measurement range with 1% of scale accuracy

• 316 stainless steel Bourdon tube resists corrosion and process media
• 304/316 stainless steel case protects internal components in harsh environments
• Dry no-fill design for straightforward handling and installation
• Polycarbonate lens rated IP54 and IP65/NEMA 4 for dust and moisture resistance
• Meets CRN, PED, and RoHS standards

Compatibility

Designed as an OEM-style replacement or new-installation industrial pressure gauge for systems requiring a 0.25-inch MNPT lower-mount connection and a 0 to 200 psi measurement range.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or instrumentation technician. Isolate and depressurize the system completely before removing or installing any pressure gauge. Use appropriate thread sealant on the MNPT connection and avoid over-tightening, which can damage the socket or distort the Bourdon tube. Verify that the process media is compatible with stainless steel wetted parts before placing the gauge in service.
