Blichmann Quick Connections inside brew kettle

[mlevings12]

Trying to make a dip tube out of what I have. Anyone know if I can use the Blichmann Quick Connection inside the brew kettle? Pretty sure it’s stainless, just can’t find anything on the temperature dance of the rubber part. Any thoughts?

The website says the grip is silicone, which I believe is stable and non-reactive up to 300C, so hoping I’m good.
