    Sealing petrol fittings?

    Screw in fuel fittings, should I use PTFE tape? I've asked it before but can't remember.

    I think PTFE dissolves doesn't it ? I think you can use stuff like Bosswhite plumbers paste. In reality it should seal by itself unless there's split /burr or suchlike?

    PTFE itself is not affected by petrol or any other solvents I've come across. I've machined up lots of PTFE parts for motors -the pads on the ends of fully floating Gudgeon pins, PTFE seals for blowers etc. had no problems at all with any of these. But I'm not sure what else other than PTFE is in the "ordinary" PTFE tape, so there could well be a problem with this when it's exposed to petrol.

    But I've always used the PTFE tape that's specifically recommended for use with oil and gas installations (always seems to come on a yellow spool) on petrol systems and it's been fine so far. My oldest installation has been in place for over 20 years now without any problems.

    This is the stuff I'm talking about: http://www.heatandplumb.com/acatalog/Gas_Tape.html

    I've always used the blue hylomar (I think that's it's name, it says that it's hydrocarbon resistant) without any issues.

    Used to get it from Unipart

    i have always used red hermitite ptfe rots with fuels more so diesel you cant use boss white as it is putty based also galvanising turns to mush with diesel and parafin.

    Have used PTFE tape on petrol and fuel oil with no leaks but it's not very reassuring to look at when it's gone spongey. As far as I know the PTFE for gas on yellow spools is same material but just a thicker tape and awkward to use on small diameter threads. Wouldn't feel happy using boss white but STAG similar to red hermetite is good. As long as the threads are a pretty good fit I'd be happiest using Loctite just as a back up to the thread seal itself.
