This manifold is 27" long and 2" tall.
Yes, it's perfect. In floor radiant runs within that temperature range.

The 3/4" fittings at either end are intended to both be inlets to the manifold, while the 1/2" ports are outlets. The idea is that you get more balanced flow to all outlets. If there were only one inlet and the first outlet were wide open, the outlets farther down the manifold would not see the same water pressure and flow. I've got 6-outlet manifolds for both cold and hot water supplies at home, and I just split the inlet water to go into both 3/4" fittings (using a t-splitter and extra 3/4" PEX). For unused outlets, I simply installed a stub of PEX with a plug in one end to cap off those outlets (after a ball valve, actually). For a three-port outlet manifold, you may not need to be worried about flow balance as much, though. In that case, buy a 3/4" plug and crimp on a short stub of PEX (3-4" long) with the plug in it on one end.
Easiest way is to get a pex pipe cap, put it on a short piece of pex tubing and attach that piece to the second end you want to close.
The easiest way to cap off the second 3/4" outlet/inlet is to use a piece of 3/4" pex attached to it with a test plug in the end of it. Sent from my HTC EVO 4G LTE exclusively from Sprint
Crimp manifolds will work with hePEX, but they only accept crimp fittings (not expansion fittings).
They do not. You would need to sweat ProPex adapters on the 1" copper ends.
