Wika 9745203 Pressure Gauge 2.5 in Dial 0-400 Psi Npt

Product Description

The WIKA 9745203 is a 2.5-inch dial pressure gauge built for trade professionals who need reliable, accurate pressure readings in demanding service environments. The case and all wetted parts are constructed from stainless steel, making this gauge well-suited for corrosive media and harsh installation conditions. It reads from 0 to 400 PSI with an analog dial and carries a stated accuracy of plus or minus 2.5 percent of scale. The 1/4-inch NPT center back mount connection allows direct installation into piping systems where a rear-entry port is required. HVAC technicians, plumbers, and mechanical contractors commonly specify this style of gauge for system commissioning, pressure testing, and permanent monitoring applications.

This gauge is designed for use in residential and light commercial mechanical systems where a compact, stainless steel analog pressure gauge is called for. The center back mount configuration suits panel-mounted or direct-pipe installations where the front face must remain unobstructed for easy reading. The no-fill liquid design keeps the installation simple and reduces concerns about fluid leakage in clean or food-adjacent environments. Its compact 2.5-inch dial face is easy to read at close range in tight equipment rooms or utility spaces.

Key Features

• Stainless steel case for corrosion resistance in harsh or wet environments

• No-fill liquid design simplifies installation and eliminates fill fluid concerns

Compatibility

Designed as an OEM-style replacement or new-installation analog pressure gauge for 1/4-inch NPT center back mount piping and equipment applications in HVAC, plumbing, and mechanical systems.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor. Shut off system pressure and relieve all residual pressure before removing an existing gauge or threading in this unit. Use appropriate thread sealant on NPT connections and tighten to fitting manufacturer specifications using a wrench on the gauge hex, not on the case body. Verify the pressure range of the gauge does not exceed the maximum allowable working pressure of the system being monitored.
