Wika 9832381 Pressure Gauge 0-160 Psi 4 in Dial Npt Lower Mount

Product Description

The WIKA 9832381 is a glycerine-filled analog pressure gauge designed for accurate pressure monitoring in industrial, HVAC, plumbing, and mechanical system applications. It features a 4-inch dial with a 0 to 160 psi range and a 1/4-inch NPT lower-mount connection. The 304 stainless steel case and stainless steel wetted parts provide strong corrosion resistance in wet or chemically active environments. Glycerine fill dampens needle vibration and reduces wear on internal components, making this gauge well suited for systems with pressure pulsation or mechanical vibration. Installation is performed by licensed plumbers, pipefitters, or HVAC technicians.

This gauge fits a wide range of applications where reliable pressure indication is required, including water supply systems, compressed air lines, hydraulic circuits, boiler monitoring, and refrigeration or HVAC piping. The lower-mount NPT connection allows direct inline installation on pipe runs or manifolds. The single-scale analog dial provides a clear, direct pressure reading without the need for external power. The 1 percent of scale accuracy rating meets the demands of most commercial and industrial service work.

Key Features

• 4-inch dial diameter for easy reading at a distance
• 0 to 160 psi single-scale pressure range
• Glycerine-filled case dampens vibration and protects movement from pulsation
• 304 stainless steel case and stainless steel wetted parts resist corrosion
• 1/4-inch NPT lower-mount connection for direct inline installation
• 1 percent of scale accuracy suitable for commercial and industrial service

Compatibility

Designed as a direct-mount analog pressure gauge for use with 1/4-inch NPT lower-mount gauge ports on water, air, hydraulic, and HVAC piping systems. Confirm system fluid and pressure range compatibility before installation.

Installation Notes

Installation is performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the system completely before removing any existing gauge or fitting. Apply thread sealant or PTFE tape to the NPT threads per local plumbing code and manufacturer recommendations. Do not overtighten the gauge body by gripping the case; use a wrench on the hex of the process connection only.
