Wika 9318194 Pressure Gauge 0-200 Psi 2-1/2 in Back Mount

Product Description

The WIKA 9318194 is a glycerine-filled industrial pressure gauge designed for continuous pressure monitoring in demanding mechanical and process systems. It features a 2-1/2 inch analog dial with a 0 to 200 psi single scale, providing clear readings across a wide pressure range. The brass case and copper alloy wetted parts offer solid corrosion resistance in typical plumbing, HVAC, and light industrial environments. Accuracy is rated at 1.5 percent of full scale. The acrylic lens protects the dial face while maintaining readability. This gauge is installed by licensed plumbers, pipefitters, HVAC technicians, and maintenance engineers wherever reliable pressure indication is required.

The WIKA 9318194 is suited for residential and commercial mechanical systems where a back-mount configuration is needed to mount flush against a panel or pipe assembly. It is commonly used on boilers, chillers, compressors, pumps, and hydraulic or pneumatic circuits operating within the 0 to 200 psi range. The glycerine fill dampens pointer vibration and reduces wear on the internal movement, making it appropriate for applications with pulsating or fluctuating pressure. The 1/4 inch NPT back-mount connection is a standard fitting size found throughout trade plumbing and HVAC piping systems.

Key Features

• 0 to 200 psi single-scale analog dial for broad pressure range coverage
• Glycerine-filled case dampens vibration and extends gauge service life
• 1.5 percent of full scale accuracy for reliable process monitoring
• 2-1/2 inch dial diameter for easy reading at typical service distances
• Brass case with copper alloy wetted parts for corrosion resistance in standard media
• 1/4 inch NPT back-mount connection for flush panel or pipe installations
• Acrylic lens protects dial face from dust and minor impact

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for industrial, commercial, and residential mechanical systems using standard 1/4 inch NPT back-mount connections with operating pressures up to 200 psi.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Always depressurize and isolate the system before removing or installing any pressure gauge. Apply thread sealant or PTFE tape to the NPT threads per applicable IPC and IFGC guidelines, and avoid overtightening, which can crack the brass case or damage the socket. Do not use this gauge on oxygen or acetylene service without confirming compatibility with the service medium.
