Wika 9310762 Pressure Gauge 0-800 Psi 2-1/2 in Dial

Product Description

The WIKA 9310762 is a glycerine-filled industrial pressure gauge designed for accurate, continuous pressure monitoring in demanding service environments. It features a 2-1/2 inch analog dial calibrated from 0 to 800 psi, with an accuracy rating of 1.5 percent of full scale. The brass case houses a copper alloy wetted parts assembly, and the acrylic lens protects the dial face. The glycerine fill dampens pointer oscillation caused by pulsation and vibration, making this gauge well suited for hydraulic lines, compressed air systems, and process piping where pressure fluctuations are common. A licensed plumber, pipefitter, or HVAC technician is the typical installer.

This gauge is configured for lower mount installation using a 1/4 inch NPT threaded connection, allowing it to thread directly into a tee fitting, manifold, or valve body from the bottom of the gauge case. It is appropriate for residential and light commercial plumbing, HVAC refrigerant-adjacent circuits, compressed air distribution, and general industrial process applications where the measured fluid is compatible with copper alloy wetted parts. The glycerine fill provides stable readings in high-vibration environments such as compressor rooms or pump skids.

Key Features

• 2-1/2 inch analog dial with 0 to 800 psi range for broad pressure monitoring coverage
• Glycerine-filled case dampens pointer flutter from pulsation and vibration
• 1.5 percent of full scale accuracy for reliable process readings
• Copper alloy wetted parts suitable for water, oil, and air service
• Brass case construction for corrosion resistance in typical industrial environments
• 1/4 inch NPT lower mount connection for direct inline or manifold installation

Compatibility

Designed as an OEM-style replacement or direct installation gauge for industrial pressure monitoring applications requiring a 1/4 inch NPT lower mount connection and a 2-1/2 inch dial format.

Installation Notes

Shut off and depressurize the system completely before removing an existing gauge or installing this unit. Apply an appropriate thread sealant or PTFE tape to the NPT threads before installation, following the fitting manufacturer and applicable IPC or IFGC guidelines. Avoid gripping the gauge case with pipe wrenches; use a wrench flat on the hex of the gauge connection only. After installation, pressurize the system slowly and inspect for leaks before returning it to service.
