1. O-rings: O-rings are one of the most common types of seals with a circular cross-section. They are used for static and dynamic sealing in applications such as pipes, valves, automotive engines, and hydraulic systems.
  2. Gaskets: Gaskets are flat or shaped seals used to fill and seal gaps between two surfaces. They are commonly used in pipe connections, automotive engines, and mechanical equipment.
  3. Sealing Washers: Sealing washers, made of metal or rubber, are used to provide a seal in bolt, nut, or screw connections.
  4. Shaft Seals: Shaft seals are used for sealing rotating shafts to prevent liquid or gas leakage. They are common in mechanical equipment, automotive transmission systems, etc.
  5. Piston Seals: Piston seals are used to seal the movement of pistons within cylinders, commonly found in hydraulic and pneumatic systems.
  6. Diaphragms: Diaphragms are thin membrane-like seals used to control the flow of liquids or gases. They have widespread applications in automotive parts, valves, and pumps.
  7. Dust Seals: Dust seals protect mechanical components from dust, dirt, and other contaminants. They are commonly used in bearings and joints.
  8. Guide Rings: Guide rings are used to guide the movement of pistons or rods and provide additional support and sealing.
  9. Expansion Joints: Expansion joints are used to absorb thermal expansion in pipes or containers, often found in pipeline systems.
  10. Sealing Strips: Sealing strips are often strip-shaped and used to fill and seal gaps, such as in building structures, doors, and windows.
