Wika 9310711 Pressure Gauge 0-160 Psi 2-1/2 in Lower Mount

Product Description

The WIKA 9310711 is a glycerine-filled industrial pressure gauge designed for accurate, stable pressure readings in demanding service environments. It features a 2-1/2 inch analog dial with a 0 to 160 psi range and 1.5 percent of scale accuracy. The glycerine fill dampens needle vibration and protects internal components from pressure spikes and pulsation. The brass case and copper alloy wetted parts are well suited for general industrial, HVAC, plumbing, and fluid-handling applications. A licensed plumber, HVAC technician, or pipefitter typically installs this gauge during new system commissioning or as a direct replacement on existing piping and equipment.

This gauge is configured for lower mount installation, meaning the 1/4 inch NPT male connection exits from the bottom of the case. That orientation suits panel-mounted, pipe-tee, and manifold installations where the gauge sits upright and the process connection is made from below. The analog dial and acrylic lens provide clear readings in both indoor and outdoor service conditions. It is appropriate for residential and light commercial systems wherever a compact 2-1/2 inch face gauge is specified.

Key Features

• Glycerine-filled case dampens vibration and reduces needle flutter under pulsating pressure
• 1.5 percent of scale accuracy across the full 0 to 160 psi range
• 2-1/2 inch analog dial with acrylic lens for clear, easy readings
• 1/4 inch NPT lower mount connection for straightforward pipe or tee installation
• Brass case and copper alloy wetted parts for broad fluid compatibility
• Single-scale display for fast, unambiguous pressure readings

Compatibility

Designed as an OEM-style replacement or new-installation gauge for industrial, HVAC, and plumbing systems requiring a 2-1/2 inch dial, lower-mount, 1/4 inch NPT glycerine-filled pressure gauge rated to 160 psi.

Installation Notes

Power down or isolate the system and relieve all line pressure before removing an existing gauge or making a new connection. Apply thread sealant or PTFE tape to the NPT threads per IPC and IFGC guidelines, and tighten with an appropriately sized wrench on the hex fitting — do not use the case or dial as a turning point. After installation, slowly restore system pressure and inspect the connection for leaks before returning the system to service.
