Default O-Ring for MAF?

Anyone know the part number to replace the O-Ring for our MAF sensor?
Does not seem from diagrams there is a separate item.

I found this one that cross references with many other Toyota / Lexus MAFs but unsure if its the same diameter and fit.

90099-14141

Can't find it in any diagram either, oversight? Rockauto doesn't have it either the picture shows the MAF with the O-ring on it. I found a picture do you have the old one to compare?

That does not fit, I've tried it. I bought a loose o-ring from my local auto shop to make it work.. They didn't have an exact one so I chose one with a smaller diameter than the original one and stretched over the sensor. Try to match the thickness too or the sensor won't seat.
