Yes, you were very lucky, and thanks for the safety reminder. I must add, There are so many types/sizes/shapes of "foster" fittings out there. Some connect together snugly, some loosely, some not at all. It is very frustrating. I have several new foster female fittings, that will not accept some of the male foster fittings I have. Some do fit, some seem too loose, some will not even go into the hole. I, and I'll bet many others have a bag full of fittings, and a half dozen or so, whips. Too many different threads for my poor old feeble mind. I like the idea of covering with a towel, or something similar. At least it would slow things down, if something did let loose. Like a bad road intersection, it will take many accidents, before the red light gets installed. Maybe, one day, these high pressure fittings will be tested,and standardized. Of course it would end the cheap egay items, like some of the moisture traps that have exploded recently. On and on......
