Hello to all !
I need to replace the O-rings of my two HP41 card readers.
I am aware that this subject has been earlier adressed here.
Very recently Massimo Gnerucci from Milan Italy very kindly indicated to me the following links to cover this subject:
ebay HP41 Card Reader Repair Service , ebay HP41 Drive repair Service , ebay O-Rings sold by Mark Hoskins , and Card Reader Repair Short fix Approach by Mark Hoskins .
Still, I think I also read somewhere else - but I am unable to recover this in the Archives here - that there also might exist some Teflon or Urethane O-rings.
Could anyone give me information about such ( possibly existing ) Teflon or Urethane O-rings : qualities ( namely efficiency and usable life ) and price compared to compared to conventional Rubber O-rings ?
Thank you very much in advance.
