Plumbers, HVAC technicians, and gas line service professionals rely on this type of detector for fast, reliable leak verification during installation and service calls.
This detector is suited for both residential and light commercial applications. It is commonly used during new gas line installations, appliance hookups, and post-repair pressure checks on natural gas, propane, and compressed air systems. The 2 oz bottle size makes it practical for service van inventory or bench use during shop testing of components. Its formula is compatible with all common tubing and fitting materials encountered in plumbing and HVAC work.
Designed for use on all types of tubing, valves, cylinders, pressurized tanks, and any system operating under air, gas, or oxygen pressure.
This product is applied by a licensed plumber or HVAC technician during pressure testing or leak verification. Before applying, ensure the system is pressurized to operating pressure. Brush or apply the solution around fittings, joints, and connections and observe for bubbling. Do not apply to systems that are energized with open flame nearby, and always follow local gas codes and applicable safety procedures when working on pressurized gas systems.
