Atlas Copco 0663716702,The sealing function is bidirectional. As a bidirectional sealing element, the initial compression amount during installation in the radial or axial direction determines the initial sealing capacity. The force generated by the system pressure acting on the O-ring is the total sealing force, and this sealing force increases as the system pressure rises. The leak-free sealing can achieve absolute leak-free sealing as long as the O-ring has an initial pressure. Buffering and shock absorption. By utilizing the elasticity of rubber to absorb mechanical vibrations or impacts, the rigidity collision between components is reduced. It buffers the vibration during engine operation and avoids interface loosening. System protection prevents dust, particles, water or corrosive substances from entering the equipment interior, protecting precision components. It plays a waterproof sealing role in electronic equipment and prevents rainwater or moisture from invading the circuit board.
