Wika 9768939 Pressure Gauge 0-2000 Psi 2.5in Dial Npt

Product Description

The WIKA 9768939 is a liquid-filled industrial pressure gauge designed for measuring gas and liquid system pressures from 0 to 2000 psi. It features a 2.5-inch analog dial with a stainless steel 304 case and copper alloy wetted parts, making it suitable for demanding service environments. The liquid-filled construction dampens pointer vibration and reduces internal wear, improving readability under pulsating pressure conditions. Accuracy is rated at 1.5 percent of full scale. The center back mount configuration and 1/4-inch NPT thread make it straightforward to install into a wide range of pressure ports. Installation is typically performed by licensed plumbers, HVAC technicians, or industrial pipefitters.

This gauge is suited for both residential and commercial applications where reliable pressure monitoring is required on gas or liquid lines. The 2.5-inch dial size provides clear scale readability in tight panel or inline installations. The polycarbonate lens protects the dial face in light industrial and mechanical room environments. Center back mounting allows the gauge to sit flush against panels or pipe assemblies without a protruding stem.

Key Features

• Pressure range: 0 to 2000 psi for high-pressure gas and liquid service
• Liquid-filled case dampens vibration and prolongs service life
• 304 stainless steel case for corrosion resistance
• Copper alloy wetted parts compatible with a broad range of media
• 1.5 percent of scale accuracy on single analog dial
• Polycarbonate lens for dial protection

Compatibility

Designed as a general-purpose industrial pressure gauge for use with gaseous and liquid media in systems accepting a 1/4-inch NPT center back mount connection.

Installation Notes

This gauge should be installed by a qualified plumber, pipefitter, or HVAC technician in accordance with applicable local codes and ASME B40.100 guidelines for pressure instrumentation. Isolate and depressurize the system fully before installing or removing the gauge. Apply thread sealant or PTFE tape to the NPT threads and tighten to hand-snug plus a controlled number of additional turns — avoid over-tightening, which can crack the gauge body or distort the Bourdon tube. Do not use the dial as a handle during installation.
