Components in automotive systems, designed to prevent leaks of fluids and gases between mating surfaces. Gaskets are typically flat, compressible materials placed between two surfaces to create a static seal, preventing leaks in areas like engine heads, oil pans, and exhaust manifolds. Seals, on the other hand, are designed to prevent leaks between moving parts, such as crankshafts, camshafts, and wheel bearings. They are often made from flexible materials like rubber or silicone and are shaped to create a dynamic seal. Both gaskets and seals are essential for maintaining proper pressure, preventing contamination, and ensuring the efficient operation of various vehicle systems.
