You’re right Marcel. There are many fittings, solvents and connectors that don’t meet local or international codes. Years ago I ran into the same thing at a national plumbing wholesaler. I was floored that they were selling non approved fixtures.
Roy, some folks get married to their opinions and ignore facts. 
I love you Michael! Yep!

It is a mechanical joint… the CPVC sleeve is crimped into copper adapter, it is not glued. No worse than propress copper fittings that rely on orings.
It’s not a mechanical joint if it’s solvent weld and soldered.
The solvent joint is between CPVC and CPVC, nothing wrong with that. The joint between copper and CPVC is crimped with oring.
Dang you think it would be listed as an approved fitting than.
Pro Press fittings are an approved fitting. This coupling of separate piping materials would have been better executed with a union or male/female adapters.
New fittings on the block. https://www.viega.us/en/products/Catalog/Metal-systems.html
I saw them use these at the ship yard on stainless pipe 5 years ago.
I’ve used Pro Press often at Intel and laboratories. The advantage is there was no need for a spark permit in a live plant.
Good morning Martin.
I watched them use that outside and the tools needed and had to be an expensive product to use.
The equipment is expensive. The fittings are crazy expensive. And you really should have proper training to use it as well. I use to dry fit the fitting onto the pipe and make a line with a sharpie. You have to be careful when operating the machinery because it has a tendency to twist and take the fitting with it. After the crimping if the fitting jumps off the sharpie line it’s not good.
And good morning Marcel
Another advantage is time. It takes me about 45 minutes to an hour to braze a 3 inch copper elbow. I can Pro Press the elbow in under 15 minutes. This makes a big difference when you figure labor for each man on the job is $150 an hour. No need for a firewatch so you just saved another $150 an hour.
I think that was the biggest advantage at the shipyard.
Fire on a destroyer is not a good thing.
Vega propress as been around for 20 years.
Don’t doubt it, takes 10 years for Maine to see new products, and the Naval shipyard only started using them 5-8 years ago.
Another thing to consider is just because a new product comes out does not mean that it is automatically approved by the IPC or UPC. These things take time and often local jurisdictions are 2 to 5 years behind code book publishing.
They originally came from Germany. Now they are in to Pex Fittings also.
I haven’t seen any of those and they look expensive too.
You’re not going to find those next to Shark Bite garbage in Home Depot. I only use the Pro Pex brass fittings, these look very durable.
Would than be the Portsmouth Naval shipyard Marcel? I spent some time there in 2012 doing some consulting work.
