Free Shrader Valve Refrigerant Leak Tester (Quick Tip)

Updated: Mar 2


Make a Quick Free Refrigerant Leak Tester for the Schrader Valve (Valve Core) at the Access Port. Drill an 1/8” hole in the end of an extra port cap. Screw your testing cap to the port and add a drop of bubble leak detector to see if it blows a bubble. Remove the testing cap when done. This will avoid getting any bubble leak detector in your port or on the valve core. If there is a leak present, replace the valve core using a Valve Core Removal Tool. After leak checking, add the correct port cap to seal and protect the port.
