Hi,
I would like to know if Reinforced PTFE is compatible with JP-8 and JP-10 jet fuel as well as Diesel Fuel? I am trying to find a fire safe ball valve in a 1" pipe size and the seats only seem to be in R-PTFE which does not seem to be compatible with JP-8. Any suggestions?
Thanks
Gabriel

I do agree with ione, and from experience, you can't go wrong with Viton. The only situation that I had a problem with Viton was when I had low temperatures. Other than that, it's compatible with almost everything!!  

RE: Jet Fuels

What is the reinforcement, glass fiber?  Don't know why JP-8 would attack that, nor any other hydrocarbon fuel.

Thank ione, this chart shows that JP-8 & JP-10 is ok with PTFE. This is perfect.

Now I need to find which metals are OK with JP-8/JP-10. Stainless is OK for sure but my main concern is Bronze.

RE: Jet Fuels

The engine manufacturers likely have listings of approved materials for contact with the fuel.
