teflon tubing - what type to use?

[Dennis O'Keefe]

Can anyone answer this question?

Hey Guys,
I looked at the Mcmaster-Carr site ( http://www.mcmaster.com/ ) did a search
for teflon tubing and on catalog pages 93-95 found the following types of
Teflon tubing:  Fluropolymers, Teflon, ETFE, PTFE, PFA, FEP, PVDF.  Which
kinds do we use for header to canister connection? Header to pipe on 4
strokes?

Any you smart guys know which one?
