As I say the moment any give me trouble I will strip them out. But I don't see the need when they perform so well?
Perhaps design also has something to do with it? I know my old mk 1 Vulcan uses a ptfe seal and is performing well after all these years.
I have the luxury of two identical Diana's T01s (albeit different calibres) and will definitely go the oem seal route next time around and compare.

Dave, where do you get these PTFE seals from ? The manufacturers do not supply them as they know it is the wrong material for the job. They have all been using polyurethane for years. Polyurethane and PTFE have totally different properties. If you put a piece of PTFE in a vice and squeeze it it will stay flat. Polyurethane will spring back to shape as it has a memory.
