Wika 9832399 Pressure Gauge 4 Inch 1/4 Inch Lower Mount

Product Description

The WIKA 9832399 is a glycerine-filled analog pressure gauge designed for accurate pressure monitoring in demanding industrial and mechanical service applications. Built with a stainless steel case and stainless steel wetted parts, this gauge delivers corrosion resistance and durability in wet, vibrating, or pulsating systems. The 4-inch dial provides a clear analog readout with a pressure range of 0 to 200 psi and a 1% of scale accuracy rating. The glycerine fill dampens pointer movement caused by pressure spikes and vibration, extending service life and maintaining readability. Licensed HVAC technicians, plumbers, and mechanical contractors rely on gauges of this type for reliable field and panel-mount pressure indication.

This gauge is well suited for residential and light commercial plumbing, HVAC hydronic systems, compressed air lines, and general industrial piping where accurate pressure measurement and resistance to vibration or pulsation are required. The lower mount configuration positions the process connection at the bottom of the gauge, making it a standard fit for panel installations, pipe-mounted assemblies, and manifold setups. The 1/4-inch threaded connection is a common size across a wide range of plumbing and HVAC fittings.

Key Features

• Glycerine-filled case dampens vibration and pressure pulsation for stable pointer readings
• Stainless steel case and wetted parts provide corrosion resistance in wet or chemically active environments
• 4-inch analog dial with 0 to 200 psi range and 1% of scale accuracy
• Lower mount with 1/4-inch threaded connection suits panel and pipe installations
• WIKA model 233.54 platform — a recognized standard in industrial pressure measurement

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for plumbing, HVAC hydronic, and general mechanical systems requiring a 4-inch dial, lower-mount, 1/4-inch connection pressure gauge with glycerine fill and stainless steel wetted parts.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor in accordance with applicable local codes and ASME B40.100 guidelines for pressure gauges. Shut off system pressure and bleed the line before removing an existing gauge or making the new connection. Use an appropriate thread sealant on the 1/4-inch male threads and avoid over-tightening, which can damage the gauge socket. Do not install in systems with pressure or media incompatible with the rated range or stainless steel wetted parts.
