I have a guy repowder coating my imco diverters. I have him on hold though since he told me that the coating he has is only good to 250 degrees. I'm not sure how hot those will get being water is going through them and all. Any ideas, is 250 degree powder coating good enough?

Shouldn't be a problem at all. You should be able to lay your hand on them and you couldn't do that if they were even close to 250 degrees.

You'll be fine. Had mine PC'd with no issues.

Just put them back in with the gloss black 250 degree powder coat. They look good. thanks guys.
