I don't think BP makes any 3/8" comp style fittings other than the straight variety. P-PC has probably the largest selection of the BP line and if they don't have it, it's likely no one does. I've seen this come up before and the last time it did (about a couple weeks ago, IIRC), I spent a bit of time a poked through the sites BP does have LC gear on and couldn't find anything like your asking for.
I've got 2 brand new BP 45 3/8 I.D. 5/8 O.D. Dual Rotary Compression fittings, if you want them send me a P.M. and we can set something up...
..I got them from PPCs but I ordered the wrong size...
Edit: they are 45 degree...didnt know you needed 90's until now....

It will be interesting to see those two together as the compression fitting will be almost the same height as the adaptor and might not be able to tighten the fitting all the way down depending on what your putting it on.

I am using the same 90 with a 1/2 3/4 and it fits so those should be fine. They are coming out of a swiftech Rad. It looks to have about a 1/4 inch of clearance before it would hit.
