In addition to their durability, metal oil seals also offer excellent sealing capabilities, helping to prevent the escape of oil and other fluids from equipment. This is crucial for maintaining the proper lubrication of moving parts and ensuring that machinery operates efficiently. By creating a tight seal between mating surfaces, metal oil seals help to reduce friction and wear, extending the lifespan of components and reducing the need for maintenance.

A typical drum brake line diagram illustrates several key components the brake drum, brake shoes, wheel cylinder, and the hardware kit, which includes springs and levers. The brake drum is a cylindrical component that rotates with the wheel. When the brake pedal is pressed, hydraulic pressure is generated in the brake line, pushing the piston in the wheel cylinder. This action causes the brake shoes to expand outward against the inner surface of the drum, creating friction that slows down or stops the vehicle.
