Teflon TAPE should NOT get any where near your airplane. Little pieces can break off and clog up your various filters. Fuel lube (EZ Turn) can be used on most all NPT fuel fittings. However, your flared fittings do not require any lube/sealants at all. Standard practice is to connect them dry. Teflon paste is also commonly used on NPT engine fuel fittings if fuel lube is not used there. Hope this helps.Am I suppose to use plumbers tape when screwing the "say" flop tube end to the blue fitting? If so, is it regular plumbers tape or special kind?..I am about to safety wire the fitting and wanted to make sure before proceeding..thx all
yes..thx. How about putting some proseal on the threads, making sure not to get any in the inner flop tube hole.?
1. You're going to need it at some point in the build, so why not buy it now? It only costs a few bucks for a tube that will be more than enough for the entire build.ok but...I have proseal..I don't have ez lube or the other stuff. The 800# Gorilla still can eat the banana right?
Ryan-I am really confused then on what is to be flared...I thought flareing was only done on the actual fuel tube or fuel vent tube... I am talking about screwing together to blue fittings together..the female end and the male end. How is that suppose to be flared?...
ps I order some ezturn..thx

That would be a 37.5 degree taper for the flare on aircraft fittings. The auto industry uses 45 degrees. Please be careful and don't use a 45 degree flaring tool on aircraft fittings.A flare fitting is generally on the end of an aluminum tube with a nut that fits onto the untapered thread on the male end of an AN fitting. That end has a 45 degree taper at the end of the threads that mates to the flared end of the tubing. the nut on the end of the tubing tightens onto the AN fitting. This is the one that doesn't require Fuel Lube/Tight Seal. These are torqued according to tables that I don't have handy, but are generally 1 to 1 1/2 flats past hand tight. (Look it up, don't take my word for it)!
