1" Male Sweat Copper Manifold w/ 1/2" Sweat Loops (3 Outlets)

I usually just make my own low loss header but no matter how you look at it these sure save time. The price on this is great compared to my local supply houses, and most are out of stock or don't stock them, weird. I could be wrong but I didn't see a 1" with 3/4" branches which was a bummer but they did have to 1-1/4" with 3/4" branch's. So I have read in other reviews that the spacing between the take off are sure close together, and I can confirm that's true but for me it wasn't an issue. I use taco zone valves and didn't have any issues with these. The only complaint I have is the 3/4" take offs. So I pretty much press everything now a days and every single press I did to the 3/4" copper was loose. I pressed taco zone valves and the Bluefin ball valves and ALL WERE LOOSE, even if I pressed it twice. If your soldering this isn't the issue. Just being that the Copper OD must be slightly smaller. This may affect wether I buy it again, unless it gets fixed. I would suggest SupplyHouse to get this fixed if possible or at minimum send some press stiffeners with the manifold. Not saying the stiffeners will work perfectly but they should help make it a tighter more secure press. To be clear it's very possible stiffeners may not work due to them being designed for thinner copper at standard 3/4"" OD such as baseboard.

You have to practically hammer in the fittings. The od of pipes are to big to accept copper fittings or valves. I recomend buying tees, and making your own. It is cheaper to do so.
