Badger Propel Air Fittings: DIY Rubber Washers

Unlike ordinary bike tubes, Michelin ProTek tubes have a square-ish cross section:

Michelin Protek Max Tube - carton
Michelin Protek Max Tube – carton

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:

Badger 260 Propel fitting seals - inner-tube version

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.

    1. I’ve tried moving my hands apart in front of my fafe, but it’s still blurry out there!

    1. 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 …
