Model: teflon - $1.25
If you're installing any threaded fittings, you'll need to use some teflon tape. On my kits, teflon tape is required where the thermometer threads into the tee on the combo kits as well as on the model SL and SB for welded applications. Tape is NOT required to install the WLSL kit as the threaded connection is on the inside of the vessel behind the rubber seal. This item is only to be added to an order including additional hardware items. Our teflon tape is milspec quality made in Italy, not the paper thin stuff from China. 1/2" wide by 260" long roll.
