Sealings and gaskets establish static, leak-proof joints between stationary vehicle components. These parts are critical in engine, transmission, and chassis systems – commonly found in valve covers, oil pans, intake manifolds, and axle housings. Materials range from compressed fiber, rubber, cork, silicone, and multi-layer steel (MLS) depending on temperature, pressure, and fluid resistance requirements. Precision dimensional control and surface finish are essential for effective sealing, preventing loss of fluids or gases. Many gaskets utilize coatings or embedded beads to enhance sealing performance and prevent sticking. Proper torque specifications during installation are paramount to maintain joint integrity and prevent failures.
