Better-Bottle o-rings from McMaster-Carr

Now that I've used up my hyphens for the week, I'll get on with the question.

Has anyone got a shopping list for racking adapter and closure replacement parts?

Shameless bump...

Did you ever find a replacement part? Specifically I'm looking for "Two replacement 1/2" ID O-rings for the Universal PET closure port - BB-CLZ(PET-O4)-SERV(A)" or an equivalent. I'd be happy to buy the authentic replacement, but can't seem seem to find anyone who carries it.

I was going to measure the one I had and order a bag of equivalent o-rings in silicone from McMaster-Carr, but I dropped it down the shower drain instead....

Edit: I'm guessing one of these should work: 9396K25 (nominal 1/2" ID, 11/16" OD) or 9396K208 (nominal 1/2" ID, 3/4" OD). I could just order both, but then I'd be out $20 for 150 O-Rings, at least 50 (probably 100) of which would be useless.

I have ordered direct from the BB folks when I could not find a vendor.
I think I had to call to place the order.

Thanks. I'll keep that in mind as a good option. I didn't realize they would sell direct. I'm hoping someone can confirm the specific McMaster-Carr part I need (mostly because I'm already placing an order with MMC, but also because I can probably buy 50 for the price of 2 from BB with shipping), but I'll order direct if I need to.

I called Better Bottle directly and they were more than helpful. I should have a couple of replacements on the way soon. Thanks for the advice.
