I wanted to find a way to convert from PVC to air line so I can set up a drip acclimator at an LFS I just started working at last month. I suppose what I am looking for is some sort of T like the one pictured on this page (http://www.cichlid-forum.com/articles/diy_auto_water_changes.php), but I know I won't be able to use brass fittings as it will have salt water running through it.
They call the parts "PVC Reducing Tees (½" Slip x ½" Slip x 1/8" FPT)" and "Brass male adapters 1/8 MPT x 3/16 barb".

So my two questions to start are:
-What specificly do I need/what is it called? and
-Where can I get them? (local or online)

Thanks in advance,
Jon

You should be able to mix and match PVC fittings and vinyl barbs to get to the size tubing you want. They should all use the same Male/female pipe threads (MPT/FPT) to make the job easier. You may end up having to use a lot of adapters, but it should be doable with out using brass. I have yet to see something in brass that you cant get in plastic.

yup, ether that or create a pvc plenum & just drill & rubber gromit it. your talking drip here so its subject to very little pressure & a fraction of the cost
