In this video, we demonstrate the installation and operation of a 4-inch carbon steel pressure gauge designed for industrial air compressor systems and receiver tanks. You'll see how this 0-1.6MPa gauge integrates with air compressor gauge and regulator assemblies to provide reliable pressure monitoring in real-world industrial settings. We walk through its key features, compatibility with pneumatic systems, and show practical applications in manufacturing and maintenance environments where accurate pressure control is critical for equipment safety and efficiency.
