teflon tape?

[prkaye]

For the SafeAir kit attachment to the aluminum tube on the Dynon pitot probe, for the threads on the blue AN fitting that screw into the brass hydraulic fitting, should I use Teflon tape? These ones did not come from SafeAir with teflon tape pre-applied, as other fittings in the kit did.

Teflon tape is fine for air fittings. However, do be careful to not get any tape in the system. However, teflon tape is a N0-NO on all fluid fittings on aircraft as far as I know. If some sort of thread sealant is necessary, teflon paste or the like can be used.
