Unlike ordinary bike tubes, Michelin ProTek tubes have a square-ish cross section:
So, having a defunct Michelin ProTek tube in hand, I cut, cleaned, and dissected a few inches, then punched out a set of (flat!) washers for the Badger Propel air fittings:
As with the cork version, they fit fine:
The picture is slightly fuzzy, because zooming a Pixel photo doesn’t magically create any new mmmm pixels.
I tested the washer with 45 psi air (the recommended maximum) and it holds the pressure fine. Better than a fouled ProTek valve, anyway.
Flushed with success, I preemptively replaced both OEM cork washers, an action which will surely come back to haunt me.

You don’t watch enough movies.
I’ve tried moving my hands apart in front of my fafe, but it’s still blurry out there!
Depends which PIxel you have: https://ai.googleblog.com/2018/10/see-better-and-further-with-super-res.html
TL;DR: By tracking small movements of the camera (from hand tremor or intentionally jittering the OIS) and taking multiple images, the camera can capture R G & B data for a space that’s normally a single-color subpixel.
It’s the original Pixel, bought on sale just before the Pixel 2 came out, so it lacks all the fancy new features. It also lacks the tendency for screen burn-in, which is fine by me.
A year from now it’ll stop getting security updates, by which time the battery should be completely defunct, and maybe I’ll pick up a Pixel 3 on sale just before the Pixel 4 comes out …
You fixed something that wasn’t broken? Dude!
Not once, but twice!
you know what they say — if it ain’t broken, fix it until it is!
