Hi, Good luck!
Are you able to match these two Kerf Type bubble seals? Or maybe similar?
And are these pics adequate or need additional ones?
The measurements are my best guess with a caliper.
Both of these have what feels like silicone fins on the Kerf projection.
The Small seal is 0.20 (5mm) diameter with 0.25 Kerf projection.
The Large seal has Hollow Foam Core inside, is 0.285 diameter, with Offset 1/4 Kerf projection and only has fins on one side.
Thanks, Jay
