4251186 SEAL For HITACHI EX400 6RB1

The Seal is a vital component used to prevent the leakage of fluids, gases, or other substances in various mechanical systems. Its primary function is to create a tight barrier between two surfaces, ensuring that internal contents such as oil, water, or air remain contained and do not escape or become contaminated. Seals are widely used in engines, pumps, hydraulic systems, and other industrial machinery to maintain pressure, reduce friction, and protect against external contaminants. They come in various types, such as O-rings, gaskets, and lip seals, each designed for specific applications, ensuring the efficiency and longevity of the systems they are used in.
