I once worked at a Shop that would not buy that Brand...only Penn.
They seemed to hold up better.
The last Refrigeration Shop I worked at a while ago went to the 1/4" Male Flare Model Penn and used the flexible stainless steel weave reinforced hoses. No more cap tube leaks.
Makes sense when you factor in Labor and Refrigerant cost...especially on a Rack System.
Four wheel therapy, my 1968 Camaro is gone and will be missed
