It is a drop of nylog. It ain't gonna hurt nothing.
Your also putting it on flares, gaskets, threads. Not directly into the system
You're being ridiculous. I've used it for 3 years now with no trouble.
Nylog for HFC is based on POE oil. As we know, POE oil is miscible with CFC, HCFC, and HFC refrigerants. So yes, the HFC Nylog is compatible with any refrigerant.
I went to the website and it explains a lot. Says use blue stuff for everything if you want. Like gravity said, lot less tacky. Doesn't seem to clog up as much. Also says to use it under and over teflon on pipe threads. Has anyone used it for this purpose? As a pipe thread compound that is.
The Blue Label Nylog can be used universally or specifically with an HFC bound synthetic oil system.
Blue Label is completely miscible in POE or PAG lubricants and exhibits good
stability in both mineral and alkyl benzene oils
