Wika 9311895 Pressure Gauge 2.5 in 0-30 Psi Center Back Mount

Product Description

The WIKA 9311895 is an analog pressure gauge designed for monitoring system pressure in HVAC, plumbing, and industrial piping applications. It features a 2.5-inch dial with a 0 to 30 PSI range and a 1/4-inch center back mount connection with a U-clamp panel mounting style. The steel case provides durable enclosure for the movement, while brass wetted parts resist corrosion in contact with the process media. Accuracy is rated at 3-2-3 percent of scale, meeting standard requirements for most field service and panel-mount monitoring tasks. This gauge ships as a no-fill unit with an analog dial face. Licensed HVAC technicians, plumbers, and mechanical contractors are the typical installers.

This gauge is suited for residential and light commercial HVAC systems, hydronic heating panels, compressed air lines, water supply systems, and general fluid service applications where a panel-mounted pressure indicator is required. The U-clamp panel mount style allows direct installation into a control panel or enclosure cutout, and the center back connection keeps piping behind the panel face for a clean installation. The 0 to 30 PSI range makes it appropriate for low-pressure systems such as domestic water, hydronic loops, and similar service lines.

Key Features

• 2.5-inch analog dial for easy field reading
• 0 to 30 PSI pressure range suitable for low-pressure fluid and gas service
• 3-2-3 percent of scale accuracy meets standard mechanical gauge requirements
• Brass wetted parts provide corrosion resistance against common process media
• Steel case construction for durability in panel and field environments
• U-clamp panel center back mount for clean flush-panel installation
• No-fill design requires no liquid dampening fluid

Compatibility

Designed as an OEM-style replacement or new-install analog pressure gauge for residential and commercial panel-mount applications requiring a 2.5-inch dial, 1/4-inch center back connection, and U-clamp panel mount in the 0 to 30 PSI service range.

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 gauge installation guidelines. Shut off and depressurize the system completely before removing or installing any pressure gauge. Use appropriate thread sealant on the 1/4-inch NPT connection and avoid over-tightening, which can damage the brass inlet fitting. Secure the U-clamp panel mount hardware before applying system pressure.
