Is there a preferred orientation for ball locks? For consistency, I put the "in post" to the left when viewed from the top and I use red o-rings on the "in posts" for my kegs, so I don't mix them up as badly when hooking lines up.
Sorry for the double derail of the original thread.... one use for a cornie that won't seal would be to store StarSAN in it, but like everyone noted above, I would try to fix it first....
