Howdy,
I've been a lurker here for some time - came across this recently and thought it might be interesting/useful.
While looking for some info on brewing, I found these "tri clover fittings":
They seem to be standard in brewing/dairy plant, and look very similar to the KF vacuum fittings (genderless flanges, O-ring, and clamp). They're polished for hygenic reasons, so I guess would do well for vacuum. Most importantly they're dirt cheap!
Maybe you know about them already, but they're totally new to me (in the UK, where we seem to be behind the times....)
Incidentally, no relation to the "tri laser connector" that Bones used to fix Spock's brain ;-)
Cheers,
Lindsay
