Wika 9833239 Pressure Gauge 0-160 Psi 2-1/2 in Dial

Product Description

The WIKA 9833239 is an analog industrial pressure gauge designed for monitoring gas and liquid system pressures in commercial and industrial applications. It features a 2-1/2 inch dial with a 0 to 160 psi range and delivers an accuracy of 1.5% of scale. The case and all wetted parts are constructed from 304 stainless steel, making it well suited for environments where corrosion resistance is required. A polycarbonate lens protects the dial face. The gauge is liquid filled, which dampens needle vibration and extends service life in high-cycle or pulsating-pressure installations. HVAC technicians, plumbers, and industrial service technicians are the typical installers.

The WIKA 9833239 is appropriate for residential and commercial HVAC, plumbing, hydraulic, and process piping systems where a reliable, corrosion-resistant pressure indication point is needed. It connects via a 1/4 inch NPT center back mount fitting, which allows direct panel or manifold installation. The liquid-filled design makes it a practical choice for pump discharge lines, compressor headers, and other services with pressure fluctuations or vibration. It is compatible with both gaseous and liquid media.

Key Features

• 0 to 160 psi single-scale analog dial for broad pressure monitoring range
• 2-1/2 inch dial diameter for clear field readability
• 304 stainless steel case and wetted parts for corrosion resistance
• Liquid-filled construction dampens needle movement in vibration-prone installations
• 1.5% of scale accuracy meets standard industrial measurement requirements
• Polycarbonate lens provides impact and chemical resistance
• 1/4 inch NPT center back mount for direct panel or inline fitting connections

Compatibility

Suitable for use with gaseous and liquid media in industrial, commercial HVAC, plumbing, and process piping systems requiring a 1/4 inch NPT center back mount pressure gauge.

Installation Notes

Installation should be performed by a qualified plumber, pipefitter, or HVAC technician in accordance with applicable codes such as the IPC or IFGC. Depressurize and isolate the system completely before installing or removing the gauge. Apply thread sealant appropriate for the media to the NPT threads before torquing; do not over-tighten, as over-torquing can crack the gauge body or distort the connection. Verify the operating pressure range of the system falls within the 0 to 160 psi scale before placing the gauge in service.
