Let me share something I recently learned with you. I've worked with PEX a lot, but never for heating applications, always domestic water. In the smaller 3/4" and 1/2" sizes, the fittings are pretty much all the same size, everywhere. But in the 1" size they're commonly available in both "pipe" and "fitting" sizes.The descriptions aren't that obvious, and I bought the wrong thing TWICE before I realized what I had done. The title says "1-inch x 1-inch copper fitting adapter". Unless you key in on the word "fitting" you won't realize that the part is actually 1/8" or so undersized and can't be used (without a coupler). If you're converting actual 1" copper PIPE to PEX, this is the adapter you need.

I used these adapters to connect 3/4" oxygen-barrier pex to 3/4" copper baseboard. They do that job well. Using pex for heating affords you the opportunity to see where the air bubbles are and I noticed air bubbles forming around all my adapters. I have numerous device and points to purge air from the system, and I have been unable to get the air out wherever these connectors are located. I've arrived at the conclusion that the shape of these adapters agitates the water and releases air bubbles, that eventually coalesce into a large bubble. Obviously a problem for any hydronic system, the baseboards perform less and the system becomes noisy. Its not terrible, under most circumstances I can't hear anything, but I'm a perfectionist. I do suspect this product was discontinued when this problem was discovered, and it will be replaced with a product with tapered edges.

Exactly what is needed.
from Albany, NY
I used these adapters to connect 3/4 copper to 3/4 pex. The adapters worked just as expected. They fit very well on both ends without the slop I've experienced with some other pex products.

Comments about 1/2" PEX x 1/2" Copper Pipe Brass Adapter:
Bought 2 packages of 25 pieces, when using them I noticed that there was a difference in the inside diameter. of the 50 pieces we had 7 that was too small to use. Quality control is lacking.
Bottom Line No, I would not recommend this to a friend
Pex to copper adapters

from Bisbee, AZ
These brass fittings were excellent in quality.
from buffalo new york
First time using pex. I wish the roll was more flexable, fishing in a finished wall was a pain. and you need a mess of hangers so it looks nice and neat on a long er run us the 10 ft straight for those spots. all the fitting worked like they should at a descent price... Thanks
