O2 Sensor Gaskets

[wsteele]

If anyone has a source for the crush washers (I think GM calls them gaskets) that come on OE O2 sensors, I would love to get a link.

I replaced my O2 sensors (original to my 2007 Yukon) and after getting everything put away, decided I want to reroute a couple of the connector/wiring bundles. I don't want to remove the O2 sensors until I have replacement washers in hand, so...

I checked the usual places (Napa never heard of them, RA doesn't seem to list them, The Genuine GM parts store in Amazon lists them, but are OOS.

Any leads would be greatly appreciated.

I had my O2 sensors out 2+ yrs ago and didn't see any gaskets?

I found some 18mm copper crush washers on McMaster-Carr’s website, so I ordered a bag.

Ideally I will find a source of the OE stamped washers, but if I fail at that, I suspect the copper ones will work fine, just not “all original”.

18MM crush washer- Amazon.

I was thinking of McMaster- they ship faster here than Amazon.

Amazon would have been faster here probably, but old habits die hard. They even had my old account still up.
