Wika 9699045 Pressure Gauge 0-30 Psi 4 in Dial Npt

Product Description

The WIKA 9699045 is an analog industrial pressure gauge built for trade and commercial service applications requiring accurate, reliable pressure measurement. The gauge features a 4-inch dial with a 0 to 30 psi range and 1% of scale accuracy, making it suitable for both gaseous and liquid media. The 304 stainless steel case provides corrosion resistance in demanding environments, while the copper alloy wetted parts offer broad compatibility with common plumbing and process fluids. A polycarbonate lens protects the dial face. This unit is liquid-filled, which dampens needle vibration and extends service life in high-pulsation systems. Licensed plumbers, HVAC technicians, and pipefitters are the primary installers.

This gauge is designed for industrial and commercial pressure monitoring on systems carrying gas or liquid media. The lower mount configuration with a 1/4-inch NPT male connection suits panel-mount and direct-pipe installations common in HVAC, plumbing, compressed air, and light process piping. The 4-inch dial provides clear readability at typical working distances. Single-scale analog readout keeps interpretation straightforward in the field.

Compatibility

Suitable for use with gaseous and liquid media. Designed as an OEM-style industrial pressure gauge for HVAC, plumbing, compressed air, and light process piping applications requiring a 1/4-inch NPT lower mount connection and a 0 to 30 psi range.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or HVAC technician. Isolate and depressurize the system completely before removing an existing gauge or installing this unit. Apply appropriate thread sealant to the NPT connection per local plumbing codes; avoid over-tightening, which can damage the gauge socket. On liquid-filled gauges, ensure the unit is installed in the correct orientation to prevent air pockets in the bourdon tube.
