    What was the ending soundtrack? Loved it. Also, it seems to me vibration caused the crack in the first place would you not been Better off replacing the stem entirely?

    I work on chillers too 🤜🤛
    I don't understand why manufacturers use the long stem pressure ports , it makes them too fragile .
    Had one cracked the other day as well , replaced it with a shorter stem one and strengthened it with the brazing rod .

    I was working on a small chiller system once with a bad low pressure cut out, replaced it did the normal steps. I was still above the unit and dropped a pair of big channel locks while I was on the phone with my boss at the time, it bounced off one of those fitting's and the stem completely broke it off lost 55 pounds of refrigerant.
