Gaskets and seals are available in a wide range of materils from rubber, synthetic, steel, or copper. They provide a mechanical seal between 2 surfaces to prevent leaks and allow less than perfect parts to maintain a leak proof seal. Monroe Aerospace is a stocking distributor of Aerospace and Mil-Spec hardware. We have an extensive inventory of gaskets - grommets and conical seals.
