I just got my camlock QDs from stainlessbrewing.com. I'm not sure if I like the 1/2 barb part of the female components. The bore of the barb part seems quite restricted. Can anyone compare this dimension to the ball lock QDs available from the vendors referenced here?
The barb part looks to be about a .300 inside diameter, a loss of about 40% of cross sectional diameter. Probably not too good for a pump.
