1. Type seal: mainly used for static seal and reciprocating seal. When used for rotary motion sealing, it is limited to low speed rotary seals.

2. Rectangular sealing ring: It is generally installed in the groove of the outer circle or the inner circle with a rectangular cross section to seal.

3.Y-type sealing ring: widely used in reciprocating sealing devices. In addition, there is a spring tension (spring energy storage) seal, which is a spring added to the PTF seal material, there are O-spring, V-spring, U-spring.

4. YX type sealing ring for hole: Product use: It is used for sealing the piston in reciprocating hydraulic cylinder. Scope of application: TPU: general hydraulic cylinder, general equipment hydraulic cylinder. CPU: Hydraulic cylinders for construction machinery and cylinders for high temperature and high pressure. Material: Polyurethane TPU, CPU, rubber. Product hardness: HS85±2°A Working temperature: TPU: - 40～+80°C CPU: -40～+120°C Working pressure: ≤32Mpa Working nature: Hydraulic oil, emulsion

5.YX-type hole retaining ring: Product use: This standard is applicable to the use of YX-type sealing ring when the working pressure of the cylinder is greater than 16MPa, or the function of protecting the sealing ring when the cylinder is eccentrically stressed. Working temperature: -40～+ 100°C working medium: hydraulic oil, emulsion, aquatic product hardness: HS 92±5A Material: PTFE
