ProPex fittings in Viega stainless manifold?

Harvey Ramer

Anyone know if the propex loop assembly fittings work in a viega radiant manifold?

kcopp

the fittings may not work but the tubing will fit in the manifold.. both are sdr9 tube

Uponor Manifold outlets are R20.
Viega Manifold outlets are SVC.
I am unsure of the thread differences there from a technical stance. I bet HR would have an answer to this one.

SVC = Standard Viega Connection.

I'm not sure what thread that is, probably unique to Viega.

Even if you found another connection that seemed to fit, thread pitch wise, it would not be a warrantied assembly, I suspect.

No wonder I couldn't find any information when googling SVC thread type.

the QS20 fittings will not work on Viega manifolds, or SBK.

Paul is right - these aren't compatible. The nuts should fit (I think they are all 3/4" straight threads), but that isn't enough. The diameters of the manifold end of the adapters aren't the same, so you can't get the connection to seal when mixing brands.

Thanks guys!
