Pressure/Temp. Ratings for Pex-A

Hi everyone. I know that it varies with brands, but I was looking at either Safelink or RHT Pex-A for piping Flat Pannel Rads back to manifold. I know both are OK for 180F and 100 PSI. but of course, (it is only a two story home) so the system pressure will be filled to 12 PSI. So, the maximum pressure the Pex would see is about 25 PSI. So, could the pex see 200F temps at this lower pressure OK?

    Pex ratings

    We use Viega pex and it's rated 100 @ 180* and 80 @ 200*. I think this is the common rating for most decent quality pex. If you're in doubt, call the manufacturer, they should be more than willing to divulge such info. The pex will have the rating printed right on the tube also along with the ASTM #.
