wirsbo and viega

Kevin O. Pulver

they are not exactly the same, but after I saw Hot Rod do it, I decided it was OK. I like the Viega stainless crimps and use them with Wirsbo (I can't say Uponor) tubing and my hand made manifolds. They're much easier to work with than the expanding ProPex style, and I think they look much more professional than the skinny little blask copper crimp bands that others offer. I like the Wirsbo ssc tool a lot, but they don't look as nice. Only downside to using the Viega is you need a tool for each size, and the SSC uses one tool for all sizes.

joining tubing

a home owner laid down some Wirsbo tubing... I very rarely need to join on to some tubing that I don't normally deal with... am I good to just use the viega press ring and fittings? Thanks, Gary

The viega press ring is differant than the wirsbo. Better off using viega crimp ring

Why?

What's the advantage and disadvantages in your opinion? There is a lot of Uponor people who would disagree with you...

Uponor

You cant expand the viega tubing, thats why.

You could take a wirsbo pex by copper and a viega pex by copper, swet them together and go from there. Thats if this is not in a slab. I've done this a few times

Wirsbo Pro-Press fittings don't require expansion of the tubing right?

can press

Although the official position is you can't joint them, we have had dozens of situations where Wirsbo tubing has been connected to Viega, or other types of pex using the Viega press rings and regular pex/crimp fittings- no issues.

You could also use a compression x compression union and join them that way.

GW

ok

thanks for the advice

One word: Sharkbite coupling baby!

ASTM Listing

As long as the tube and fittings are listed to the same ASTM they should work. Most PEX is lsted to F876/F877. Are you joining PEX to PEX or PEX to FostaPEX?

Yes

Hi Josh, the pro press does require expansion. It is in print in the new list price book.

Pro-pex

Josh I think you are getting Uponor (or Wirsbo's)pro-pex composite fittings mixed up with the Pro-Press system from VIEGA that is used for copper and stainless piping. Due to the inflated costs of copper stainless is now getting to be a viable substitute for copper. I had the Viega rep in several weeks ago and he said the pro-press copper and stainless will have the same ODs so the same press tool will work for both (very cool)

Pro-pex has been around for a number of years now from Uponor (wirsbo) it is a composite material that is very cost effective as an alternative to their brass fittings.

The proper way to join the piping would be to use the MRP (manufacturers recommended procedures) this would insure that you are not voiding the warranty by mixing and matching. I would watch out for Sharkbites as we are starting to see failures with conditioned , R/O and other treated water. If this is a glycol system I would definitely avoid the Sharkbites. We stopped using them as they are weeping and creating callbacks in many applications.

We never put Sharkbites in walls or concealed areas as we felt they were not a proven system. This worked in our favor on callbacks.

Both Viega and of course Wirsbo have excellant pex systems and both have jointing systems that are proven in the field. Unless you want to void the warranties and assume the liability of doing so don't mix and match!
