What are the common seals?
A seal is a material or component used to seal an object or container. There are many types of seals, and different seals can be selected according to different application scenarios and requirements. Here are some common types of seals.

1. O-ring
The O-ring is an annular rubber seal with good elasticity and wear resistance. It is usually used in static seals and low-speed rotary seals, such as faucets, automotive engines, hydraulic systems, etc.
2. U-ring
A U-ring is a U-shaped rubber seal that is often used in equipment such as hydraulic cylinders and pneumatic components. It has good sealing and compression resistance, and can withstand large pressure and extrusion force.
3. V-ring
V-ring is a V-shaped rubber seal, usually used in high-speed rotating seals, such as bearings, pumps and other equipment. It has good wear resistance and oil resistance, and can withstand large radial and axial forces.
4. Oil seal
An oil seal is a seal used to prevent leakage of lubricating oil, and is usually used in automobiles, mechanical equipment, etc. It consists of a metal shell and a rubber sealing ring, which can withstand large pressure and temperature changes.
5. Magnetic seal
Magnetic seal is a technology that uses the principle of magnetic force to achieve sealing, and is often used in high-speed rotating equipment. It consists of a magnetic rotor and a non-magnetic stator, which can achieve non-contact sealing and has good wear resistance.
6. Bellows
Bellows is a tubular seal made of metal material with good elasticity and corrosion resistance. It is usually used for sealing under high temperature and high pressure environment, such as boiler, petrochemical and other fields.
7. Soft packing
Soft packing is a flexible seal made of fiber, rubber and other materials, usually used in pipes, valves and other equipment. It has good elasticity and corrosion resistance, and can adapt to sealing surfaces of different shapes and sizes.

The above are some common types of seals. Different application scenarios and requirements require selection of suitable seals to ensure the normal operation and safe use of the equipment.
