Wika 50128787 Pressure Gauge 2.5 in Dial 0-6000 Psi Lower Mount

Product Description

The WIKA 50128787 is a glycerine-filled analog pressure gauge designed for demanding fluid and gas system monitoring. Built with a stainless steel case and stainless steel wetted parts, this gauge is well-suited for applications involving corrosive media, vibration, or pressure spikes where liquid filling is required to dampen pointer movement and protect internal components. The 2.5-inch dial provides a readable display, and the lower-mount 1/4-inch threaded connection simplifies installation in tight panel or pipe configurations. Accuracy is rated at plus or minus 2.5 percent of full scale across the 0 to 6000 psi range. WIKA model 233.30 is the underlying series designation for this gauge.

This gauge is appropriate for use in hydraulic systems, high-pressure water systems, compressed gas lines, industrial process piping, and mechanical equipment requiring continuous pressure monitoring. The glycerine fill makes it particularly effective in environments with pulsating pressure or vibration, such as pump discharge points or compressor outlets. It is suited for both commercial and light industrial installations where a compact, corrosion-resistant gauge is needed at a high-pressure range up to 6000 psi.

Key Features

• 0 to 6000 psi pressure range covers high-pressure hydraulic and gas applications
• Glycerine liquid fill dampens pointer flutter in vibrating or pulsating systems
• Stainless steel case and wetted parts provide corrosion resistance in harsh media
• 2.5-inch analog dial delivers clear, at-a-glance pressure readings
• Lower-mount 1/4-inch threaded connection for direct pipe or panel installation
• Plus or minus 2.5 percent of scale accuracy for reliable field readings

Compatibility

Designed as an OEM-style replacement or new-installation gauge for systems requiring a 1/4-inch lower-mount connection and a 0 to 6000 psi range with a 2.5-inch dial format.

Installation Notes

Installation should be performed by a qualified technician familiar with the pressure system being serviced. Always depressurize and isolate the system before removing or installing any pressure gauge. Apply appropriate thread sealant to the 1/4-inch NPT connection per system requirements and applicable codes. Do not overtighten the gauge body; use a wrench on the hex fitting, not the case.
