so had them delivered today, thing of beauty ?  Anywhoo, I will be feeding them from one end only, and will put a short bit of copper on the other to support the manifolds.  Here is the stupid question:- what fittings do I need to feed the water in and for copper at tother end?  these are the bad boys https://www.jtmplumbing.co.uk/pipe-fittings-c433/hep2o-brass-manifolds-c661/hep2o-four-port-valved-manifold-15-tm-tf-fp-p21691 

You will need a male BSP connector and a reel of ptfe tape.

Male one end and female the other end. Just fit a cap end on the blank bit you wish to use as a support. You can also use brass 1" munson rings to go around the whole thing if that is easier?

Also think about adding a drain tap on the end of each manifold. Makes draining down easier.
