Wika 9833434 Pressure Gauge 0-200 Psi 4 Inch Dial Npt

Product Description

The WIKA 9833434 is a liquid-filled industrial pressure gauge designed for accurate pressure monitoring in both gaseous and liquid service applications. It features a 4-inch analog dial with a 0 to 200 psi range and delivers 1% of scale accuracy. The stainless steel case and stainless steel wetted parts make it suitable for demanding environments where corrosion resistance is required. A lower-mount, 1/2-inch NPT threaded connection allows direct inline or manifold installation. The liquid-filled design dampens needle vibration, extending service life in high-pulsation systems. Licensed technicians, pipefitters, and industrial maintenance professionals typically install this gauge.

This gauge is suited for residential and commercial plumbing, HVAC, and light industrial piping systems where monitoring operating pressure is critical. The 4-inch dial provides clear readability in tight mechanical rooms and equipment spaces. Lower-mount configuration positions the gauge inline with the pipe run, which is a common installation geometry in process and HVAC applications. It is compatible with gaseous and liquid media, giving installers flexibility across system types.

Key Features

• 0 to 200 psi single-scale range on a 4-inch analog dial
• 1% of scale accuracy for reliable pressure readings
• Liquid-filled design reduces needle flutter in high-pulsation or vibration-prone systems
• Stainless steel case (Grade 304) and stainless steel wetted parts for corrosion resistance
• Lower-mount 1/2-inch NPT connection for straightforward inline installation
• Polycarbonate lens for impact and chemical resistance

Compatibility

Designed for use with gaseous and liquid media in industrial, HVAC, and plumbing piping systems equipped with 1/2-inch NPT lower-mount gauge ports.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or HVAC technician following applicable IPC and IFGC guidelines. Always depressurize and isolate the system before installing or removing a pressure gauge. Use an appropriate thread sealant on the NPT threads and tighten with a wrench on the hex flats only — do not torque against the gauge case or dial. Verify that the gauge pressure range and wetted-parts materials are compatible with the system medium before commissioning.
