Wika 9834087 Pressure Gauge 160 Psi 4.5 Inch Dial

Product Description

The WIKA 9834087 is an analog pressure gauge with a 4.5-inch dial, designed for industrial and mechanical system monitoring applications. It reads from 30 inches of vacuum through 0 to 160 psi, making it suitable for both vacuum and positive pressure measurements on a single dial. The thermoplastic case keeps weight low at 2 pounds while providing reasonable resistance to moisture and mild chemicals. Accuracy is rated at 0.5 percent of full scale, which meets the needs of most HVAC, plumbing, and light industrial service work. A rear flange mount configuration allows panel or wall installation with a clean face-forward presentation.

This gauge is used in residential and light commercial applications where a surface-mounted or panel-mounted pressure indicator is needed. Typical install scenarios include boiler system monitoring, chilled water loops, compressed air lines, and general mechanical room instrumentation. The rear flange mount style suits control panel cutouts and enclosure doors where a flush or near-flush installation is preferred. The 1/4-inch NPT rear connection keeps the piping run behind the mounting surface, reducing exposed hardware at the gauge face.

Key Features

• Compound range: 30 inches vacuum to 160 psi on a single dial
• 4.5-inch analog dial for easy reading at distance
• 0.5 percent of scale accuracy for reliable system monitoring
• Rear flange mount for panel and enclosure installations
• Thermoplastic case — lightweight at 2 pounds
• 1/4-inch NPT rear connection

Compatibility

Designed as an OEM-style or replacement analog pressure gauge for residential and light commercial mechanical systems requiring a 4.5-inch rear-flange-mount instrument with a 1/4-inch NPT connection and a 0-to-160 psi range.

Installation Notes

A licensed plumber, HVAC technician, or qualified mechanical contractor should install this gauge in accordance with applicable local codes and ASME B40.100 gauge installation guidelines. Isolate and depressurize the system fully before removing any existing gauge or fitting the new one. Use an appropriate thread sealant on the NPT connection — do not overtighten, as thermoplastic-case gauges are not designed for pipe-wrench torque on the case itself. Verify the system operating pressure falls within the gauge range before returning the system to service.
