Correct o-ring size for HP-65 and HP-67 card readers

[AndiGer]

Hi Alberto,

Welcome back, great to hear from you again.

Searching the articles you can find an article on the HP-82104A O-ring size.

Searching the net for "o-ring s006" will give (for me in Germany at least)
https://www.lesker.com/flanges/silicone-...art/o-s006
where you find the exact measuring including mm and inches.

Buy from the seller of your confidence :-).
