anyone have first hand experience in this area? specifically does chloride diffusion present an issue in ptfe vs eptfe? (thinking gaskets here) eptfe is much more porous, but in a gaske thats compressed, how much an issue is this?
i need a brain dump on the topic. tia
Thanks for your insightful response. these gaskets were invented before eptfe was even a thing so perhaps there are better alternatives to them now. however i understand that eptfe is a very porous material under a microscope compared to virgin ptfe which is more dense. do you know how that...
i posted in M.E section but not any replies there. does anyone have experience using the task line gasket? it's a ptfe gasket with a metal ring inside and the teflon is molded around it. it gives the ptfe better creep and relaxation characteristics but makes the gasket nearly blow out proof...
The sketch isn’t a good design, but I’ll entertain it - the answer is you need to account for some, but not all. You do need to estimate deflection due to gaps in the thread, and some deflection of the thread. (This gives you deflection - you calculate the loss in preload force by F=kx; your...
a greybeard i work with is telling me to research the taskline gasket as he's never seen one fail by blowout. does anyone have any experience? we switched most of our plant over to cut eptfe sheet w/ fillers. this was before my time.
fyi taskline gasket is molded ptfe but has a perforated...
