Advantages: simple, small friction without any seals.

Disadvantages: leakage cannot be completely prevented, and the tightness cannot be improved with the increase of pressure.

Application: environment with small diameter, low pressure, fast speed and low sealing performance, such as reversing valve and hydraulic pump (column

Plug pump)Hydraulic motor, etc.Hardly used in the cylinder.

2. O-ring seal:

Generally made of rubber.

Advantages: simple structure, good sealing performance and small friction.

Disadvantages: can not compensate after wear, short life.

Application: it can be used for linear reciprocating and rotary motion, but more for fixing seals, such as seals between pipelines, cylinder heads and cylinder liners.Or for low-grade, non-critical devices.
