New O-ring for MAF sensor

[komichal]

Hi folks,
I have been cleaning my MAF sensor (never done before on this particular car, 80,000 miles and it was gunky af). Anyway, I was a bit surprised when I pulled the MAF out and the o-ring sealing it inside the airbox was broken...

So, I cleaned the MAF, glued the o-ring together , put everything together. Engine works, no engine error. But next time I am under the hood I would like to replace that o-ring with a new one. Or at least I would like to have one o-ring as a spare, just in case.

The problem is - it seems I cannot find the o-ring itself as a spare part! I can find it for several other MAFs but not for my 22204-0J010. I am even considering buying some Chinese MAF clone from ebay for 20 bucks and use just the o-ring but that is rather inefficient solution.

Any idea where to get that o-ring? Just to make it clear, here is a picture showing which o-ring I have in mind. Thanks!
