    R-507B doesn't exist, at least last I checked...

    Did you mean R-407B? It has been quite some time since I've seen it.

    Did you mean 507 A never heard of 507 B.?
    I love the smell of phosgene first thing in the morning:

    R-507b ?

    At minus 70F I believe you mean R-508B, and that refrigerant is also know as SUVA 95 and can be purchased at any refrigerant wholesaler selling DuPont refrigerant. P/T charts are also in the ASHRAE Fundamental Handbook.

    Sell the customer the jug depending on your area it can take a day or two to get so they will always have it on hand. If it’s a good customer sell it to them a little over cost that way you don’t have dead inventory . If it’s a bag customer tell them to call someone else.
    Honeywell you can buy better but you cant pay more

    I told my wife when i die to sell my fishing stuff for what its worth not what i told her i paid for it

    Don’t think that’s going to happen unless he has r23 or something older and more expensive
