This SAE Aerospace Information Report (AIR) presents preferred practices for sealing of aircraft integral fuel tanks, including rework of applied fuel tank seals. It addresses engineering designs for integral fuel tanks as they are currently found in practice; and this document discusses the most practical and conservative methods for producing a reliable, sealed system. Design preferences for optimum sealing are not within the scope of this document. Such discussions can be found in the Air Force sponsored handbook, entitled Aircraft Integral Fuel Tank Design Handbook, AFWAL-TR-87-3078. Key objectives of the fuel tank sealing process are to produce a sealing plane that is leak-free and corrosion resistant, especially at fastener locations, at environmental and operational conditions expected for the life of each air vehicle.
This specification establishes the requirements for an expanded polytetrafluoroethylene (EPTFE) in the form of sealing tape, gaskets, or sheets requiring no mixing or curing.

This specification covers polythioether rubber fuel resistant sealing compounds, supplied as a two-component system, which cure rapidly when exposed to a cure on demand (CoD) light source used to initiate a reaction that generates crosslinking of sealant polymers. Type 2 compounds also cure at ambient conditions, without light exposure.
