Wika 9310703 Pressure Gauge 0-100 Psi 2.5in Dial Lower Mount

Product Description

The WIKA 9310703 is a glycerine-filled industrial pressure gauge with a 2.5-inch analog dial, designed to measure pressures from 0 to 100 psi. It features a lower-mount, 1/4-inch NPT connection, a brass case, and copper alloy wetted parts. The glycerine fill damps needle vibration and protects internal components in wet or high-cycle environments. Accuracy is rated at 1.5 percent of scale. This gauge is installed by licensed plumbers, HVAC technicians, pipefitters, and industrial maintenance professionals on pressurized fluid and gas systems requiring continuous local pressure indication.

The 9310703 is suited for residential and light commercial HVAC systems, plumbing lines, compressor manifolds, and general industrial process piping where a compact, reliable pressure indication point is needed. The lower-mount NPT connection allows direct installation into a tee, riser, or pressure port without additional fittings in most standard applications. The acrylic lens provides a clear dial face for field reading under typical service conditions.

Key Features

• Glycerine-filled case damps needle vibration in pulsating or high-cycle systems
• Copper alloy wetted parts suitable for water, air, oil, and compatible fluid service
• Brass case construction provides corrosion resistance in typical field environments
• 1.5 percent of scale accuracy across the 0 to 100 psi range
• Lower-mount 1/4-inch NPT connection for direct inline or port installation
• Acrylic lens with analog dial for clear, unobstructed field reading

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for industrial, commercial, and residential systems requiring a 1/4-inch NPT lower-mount connection and a 0 to 100 psi range.

Installation Notes

Isolate and fully depressurize the system before removing or installing this gauge. Use appropriate thread sealant rated for the system media on the NPT threads. A licensed plumber, pipefitter, or HVAC technician should perform the installation in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Do not overtighten the NPT connection, as this can damage the brass case threads.
