Testo 316-3 and Nylog Blue – HVAC Know It All

I brought a couple of my favourite products together for this demo. The 316-3 can pick up leaks as small as 0.15 oz annually. Applying Nylog Blue to this fitting instantly seals the leak. Great for gaskets and all types of threads. With quality tools and products, you can step up your game quite easily.
