Per Vendor: DC730 is fuel resistant and it is an adhesive similar to other silicone RTV materials. The fuel resistance is an added benefit of the DC730 that goes above and beyond typical silicone RTV's.

As long as the tube is sealed it should be fine to reuse again later. Keep in mind once opened it would reduce the shelf life.

Have used this on three E/A-B aircraft. This product guarantees there will not be a fuel leak on any fitting to which its applied. (Six nylon fittings in my aircraft shrank due to age, and all four were sloppy-loose, yet the rubbery aspect of this compound kept the fuel system sealed until they were discovered and replaced.)

I'm just delighted to find out Aircraft Spruce carries this item (Dow Corning 730 RTV). I had a difficult time find anyone who had it in stock. I placed my order on Friday and had it delivered on Monday. Great service!
