 Viega Pureflow Pex Temperature Rating
Author: schwansa67 (WI)

There is some work to be done at a farm milk parlor setting replacing few faucets. The hot water is around 180 degrees for sanitation purposes, and around 70 psi. Currently all pex with brass (non viega) fittings with stainless side pinch crimp clamps.

My question is, will my viega pureflow press fittings with attached sleeves work under that high temp or not?

I also want to install the viega pureflow press ball valves w/attached sleeves on 2 faucets. Obviously, cold side will be fine,

but will the 1/4 turn ball valves take the 180 degree water without internal leaking?

I don't want problems with the valves leaking and or fittings blown due to high temperature.

Thank you for any advice!
