I've noticed that a lot of brass fittings have a maximum temperature that's less than what I'd want in my cooling system. I bought a nice brass fitting at Menard's and noticed the low spec, and emailed the company asking about it, since my pressure would be super low. They said that they stand by their rating, so I didn't use it..... of course, I was probably talking to a customer service person giving a standard answer and not an engineer.
