Wika 9833646 Pressure Gauge 0-30 Psi 2.5 in Dial Lower Npt

Product Description

The WIKA 9833646 is an analog industrial pressure gauge designed to measure pressures from 0 to 30 psi. It features a 2.5-inch dial with a single scale and a stainless steel case rated at 304 grade, making it suitable for demanding environments where corrosion resistance is required. The wetted parts are also stainless steel, ensuring compatibility with a wide range of gaseous and liquid media. With a 1.5% of full-scale accuracy rating and a liquid-filled construction, this gauge delivers steady, dampened readings under vibration or pressure fluctuation. It mounts via a lower 1/4-inch NPT connection and is installed by licensed plumbers, HVAC technicians, and industrial service professionals.

This gauge is well suited for residential and light commercial plumbing, HVAC, refrigeration, and process applications where accurate low-pressure monitoring is required. Liquid-filled gauges are particularly effective in pump installations, compressor systems, and piping runs subject to vibration or pulsation. The polycarbonate lens provides impact resistance in typical service conditions. The compact 2.5-inch dial is readable in tight panel or pipe installations where space is limited.

Key Features

• 1.5% of full-scale accuracy for reliable process monitoring
• Liquid-filled case dampens needle flutter from vibration or pulsation
• 304 stainless steel case and stainless steel wetted parts for corrosion resistance
• Lower mount with 1/4-inch NPT connection for standard pipe thread fitment
• Polycarbonate lens provides impact and shatter resistance
• Compatible with gaseous and liquid media

Compatibility

Designed for use with gaseous and liquid media in industrial, HVAC, plumbing, and process piping applications requiring a lower-mount 1/4-inch NPT pressure gauge with a 0 to 30 psi range.

Installation Notes

Installation should be performed by a qualified plumber or instrumentation technician in accordance with applicable codes, including IPC and ASME B40.100 guidelines for pressure gauge installation. Isolate and depressurize the system fully before removing any existing gauge or fitting the new gauge. Apply an appropriate thread sealant or PTFE tape to the NPT threads, taking care not to over-torque the fitting or allow sealant to enter the pressure port. Liquid-filled gauges should be mounted in the orientation specified by the manufacturer to prevent fluid migration or air pockets that could affect accuracy.
