Using A Thread Sealant (Nylog) To Seal Refrigerant Leaks

Nylog Blue is a thread sealant and assembly lubricant manufactured for the HVAC and refrigeration trade. Nylog Blue is made from POE refrigeration oil and can help seal brass caps, flares, gaskets and all kinds of threads to help avoid refrigerant leaks. It also helps to keep seals lubricated and never hardens.

I made this video as there seemed to be confusion amongst many on its uses and applications. I have been using the product since the early 2000s and have never seen it damage system internals.
