Wika 9832411 Pressure Gauge 0-400 Psi 4 in Dial Lower Npt

Product Description

The WIKA 9832411 is a glycerine-filled industrial pressure gauge designed for demanding mechanical and process applications. It features a 4-inch analog dial with a 0 to 400 psi range and a 1/4-inch NPT lower-mount connection. The stainless steel case and stainless steel wetted parts provide corrosion resistance in wet or chemically aggressive environments. Glycerine fill dampens pointer movement under pulsating or vibrating conditions, extending service life and maintaining readability. Accuracy is rated at 1 percent of full scale. Licensed HVAC technicians, plumbers, pipefitters, and mechanical contractors install this gauge in refrigeration, compressed air, water, and general industrial pressure systems.

This gauge is suited for residential and light commercial mechanical systems where a reliable analog pressure reading is required. It mounts from the bottom of the gauge body, making it appropriate for panel-mount or pipe-top installations where overhead reading is needed. The glycerine fill makes it especially well-suited for pump discharge lines, compressor outlets, and other high-vibration service points. The 4-inch dial provides clear readability at typical service distances. No specific model compatibility was stated in the product data; consult your system documentation to confirm pressure range and connection suitability before installation.

Key Features

• Glycerine-filled case dampens pointer vibration and pulsation for stable readings
• Stainless steel case and stainless steel wetted parts resist corrosion in wet or aggressive environments
• 304 stainless steel case grade provides durable, long-term field performance
• 1 percent of full-scale accuracy for reliable pressure monitoring
• 4-inch analog dial with single scale for clear readability
• 1/4-inch NPT lower-mount connection for standard pipe or panel installation

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for industrial, mechanical, and trade applications requiring a 4-inch dial, 0 to 400 psi range, 1/4-inch NPT lower-mount connection, and glycerine fill.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or mechanical contractors in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Shut off and depressurize the system completely before removing an existing gauge or making a new connection. Apply thread sealant or PTFE tape to the NPT threads and tighten to snug with a wrench, avoiding over-tightening which can crack the socket. Do not use the gauge body or dial housing as a wrench point; use the hex flats on the gauge socket only.
