Need to check gas line pressure with precision? This CARBO 4-inch pressure gauge is a professional-grade tool built for the job. It has a clear, easy-to-read 4-inch dial with a dual scale showing pressure in both PSI (up to 15) and inches of Mercury (up to 30). The accuracy is within 1%, which is excellent for testing and diagnostics. It comes as a complete assembly with a sturdy chrome-plated steel valve body and a 3/4-inch female NPT connection, ready to screw right into your gas line test port. The gauge case itself is made from corrosion-resistant stainless steel 304, and it features a red pointer that can sometimes hold a 'memory' of the peak pressure reached. The internal wetted parts are brass/copper alloy, suitable for gas. It's designed for working temperatures from -4°F to 140°F. Whether you're a plumber, HVAC technician, or a savvy DIYer working on a gas appliance installation or leak check, this reliable, durable gauge gives you the accurate readings you need to work safely and confidently.
