My question is, does acrylic tubing in the US use the same dimensions/standards as the copper tubing? Will something like this work for 1/2" copper tubing bought from the Home Depot or Lowes in the US?
Its either that, or I stick to the Festo fittings.
Acrylic tubing sold in the states is sold by ID OD.
I wouldn't speculate on the PrimoChill fittings, until they are avaiable and can be purchased, to see if using copper is viable.
believe me I know the difficulties of sourcing the proper materials in the U.S. your best bet is going to be online ordering, not Home Depot.
One final recommendation I can give to everyone looking to do a ridgid style loop, is to
Pick the fittings you like, then source the tubing to match the fittings. Some fittings will work with both acrylic and copper. Acrylic is very inexpensive when compared to copper, I have used acrylic for mocking up some complex bends, then re created in copper so as not to waste a piece if I messed up a compound bend.
