    Having a bit of difficulty on another (NON-COMPETING FORUM, let me stress that fact!), regarding use of shaft-seals employing other than factory-specified materials. I happen to have experience along those lines, but rather than jump in and return here looking like the proverbial "returned asshole", I seek specific technical info first. Does anyone have a background which involves the use of Teflon and/or Viton as the elastomeric sealing element employed in rotating shaft seals? Or, at least, expertise regarding such sealing information using conventional materials such as Buna N (nitrile) rubber, or others elastomers (polyacrylic), in deference to fluoroelastomers?

    Thanks! jocular

    I suspect it is not relevant to what you are after, but I have passing knowledge (and access to more) on HNBR/NBR seals in downhole equipment applications on rotating bearings, but no knowledge of flouroelastomers.

    When it comes to embroidery in Flanders in the early 13th century I am at a complete loss.
