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
