AED Performance was founded with one basic premise in mind -- the manufacturing of high quality components at competitive prices. You can see the results of that dedication and focus in their carburetors and components, like these needle and seat gaskets. These nylon gaskets are reusable, and designed to work optimally with AED needles and seats for gasoline and alcohol carburetors. For professional builders or enthusiasts, this is a bulk package that includes 10 pairs of gaskets.
