Wika 9833442 Pressure Gauge 0-300 Psi 4 in Dial Npt

Product Description

The WIKA 9833442 is a liquid-filled industrial pressure gauge designed for accurate, reliable pressure monitoring in demanding service environments. It features a 4-inch analog dial with a single scale reading from 0 to 300 psi and delivers 1% of scale accuracy. The lower-mount, 1/2-inch NPT connection makes it straightforward to install directly into process lines. The stainless steel case and stainless steel wetted parts resist corrosion and contamination, and the liquid fill dampens pointer flutter caused by pressure spikes or vibration. Installed by licensed plumbers, pipefitters, HVAC technicians, and industrial maintenance crews, this gauge is built to handle both gaseous and liquid media.

This gauge is suited for residential and commercial applications where a robust, corrosion-resistant pressure-indicating instrument is required. Typical installations include water supply systems, compressed air lines, hydraulic circuits, chemical feed systems, and HVAC hydronic loops. The lower-mount configuration fits standard panel or pipe nipple installations, and the polycarbonate lens protects the dial face from impact and moisture. It is compatible with both gaseous and liquid media as specified by the manufacturer.

Key Features

• 1% of scale accuracy for reliable pressure indication
• Liquid-filled case dampens vibration and pressure-spike-induced pointer movement
• 304 stainless steel case and stainless steel wetted parts for corrosion resistance
• 1/2-inch NPT lower-mount connection for direct in-line installation
• Polycarbonate lens protects dial face against impact and moisture
• Compatible with both gaseous and liquid media

Compatibility

Designed for use with gaseous and liquid media in industrial and commercial pressure-monitoring applications requiring a 1/2-inch NPT lower-mount connection.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified maintenance technician. Isolate and depressurize the system fully before removing or installing any pressure gauge. Apply appropriate thread sealant to the NPT threads in accordance with the applicable plumbing code before threading the gauge into the fitting. Do not over-tighten the connection, as stainless steel threads can gall under excessive force.
