    i would use zoom spout oil over leak lock any day of the week!!!!!!

    you should use Nylog for all refrigerant threading, its the best product for the job!!!!
    Agree.

    Particularly mini-splits.
    JP that's what all the trainers say but when pressed I have not found any to be other than 45* which is pretty standard. Years ago the LG guy was all about making sure everyone was using the special flaring tool he said 45* turns out that's the same as every flaring tool that we have all been using.
    And I never use the factory flares on the line sets it is only there to hold the nut on IMO.

    There are two Nylogs. Blue for HFCs and Red for CFC/HCFCs.
    I like them.

    though it does suggest here: http://www.refrigtech.com/Product/Se...nylog_red.html

    that is somewhat usable for POE lubricated systems.

    Why not just buy both and have full compatibility? They cost less than ten bucks each.
