Managed to get a direct link to what I'm looking at:
http://www.mcmaster.com/asp/framewor...36,237,238,239
middle of the page, under Barbed Hose Connection
I checked USplastics.com ... and managed to find this:
http://www.usplastic.com/catalog/cat...ittings&Page=1

hmmmm
I'm also looking for some flowmeters too ... and they look like they'll cost me an arm and a leg too :-\ damnitall!
