Materials used in JET Fuel and JET Fuel System contact
(OP)
I was trying to find specification of materials which are using in aircraft jet fuel systems. What kind of steel or rubber is using for tanks / seals / hoses?

RE: Materials used in JET Fuel and JET Fuel System contact
AMS-S-8802 - SEALING COMPOUND, TEMPERATURE RESISTANT, INTEGRAL FUEL TANKS AND FUEL CELL CAVITIES, HIGH ADHESION
Tubing is generally stainless type 321 for weldability without objectionable heat sensitization.

Maybe all of polymer materials may be used in fuel system when they meets AMS-S-8802 or other standarts for materials?
321 stainless - thanks for this tip.
Some parts in engine has contact with fuel - eg piston usually made aluminium alloy. The same materials are using in engines for planes?

Polyethylene is not approved for holding fuels since it will fail at temperatures around 140 degrees F
As for other kinds, the Concorde was fitted with a special kevlar-rubber composite on the lower half of the fuel tanks above the landing gear after the paris takeoff accident, this was for armor and not for regular lining, but it goes to show these materials are fuel resistant

that link might be useful, scroll down to where it says flouritanted network polymers.

Just about any steel (and frankly, any common metal - e.g. brass, aluminum) is okay for use in fuel systems, with the caveat that some fuels have fairly corrosive contaminants and/or constituents. Sulfur contaminants especially will corrode copper-base alloys.
