i am setting up a brewing stand. im using thermoplastic tubing for all my hot and cold wort lines with stainless hose barbs and quick disconnects. i have to thread some stainless fitting onto my march pump and onto my blichmann therminater. will teflon tape be good and withstand the heat of boiling wort and then be able to be cleaned and sanitized without having to redo the fittings.
is teflon tape acceptable for my stainless connections.
Metal on metal especially the same metal is bad my old engineer dad told me. The tape can handle the heat but you might have to redo fittings on sanitary critical fittings if sloppily wrapped.
Metal on metal causes galling which basically cold welds the pieces together (bad). The teflon acts both as a lubricant and a sealant and will work fine in this application.
Use teflon tape and use the commercial type. Thread tape is appropriate for use on tapered threads, where it is the thread itself that provides the seal surface. It is not required on parallel threads - parallel threads will not seal effectively themselves, even with tape.
