In addition to the general requirements of the sealing ring material, the sealing ring should also pay attention to the following conditions:

(1) Full of elasticity and resilience;

(2) Appropriate mechanical strength, including expansion strength, elongation and tear resistance.

(3) The performance is stable, it is not easy to swell in the medium, and the thermal shrinkage effect (Joule effect) is small.

(4) It is easy to process and shape, and can maintain precise dimensions.

(5) Does not corrode the contact surface, does not pollute the medium, etc.

The most suitable and commonly used material to meet the above requirements is rubber, so the sealing ring is mostly made of rubber. There are many types of rubber, and new types of rubber are constantly appearing. When designing and selecting, one should understand the characteristics of various rubbers and choose them reasonably.

U-shaped ring

Commonly used in the manufacture of reciprocating seals in hydraulic systems. It is widely used in the sealing of hydraulic cylinders in construction machinery.

O-ring

Mainly used for static sealing and reciprocating motion sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing devices.

Rectangular sealing ring

It is generally installed in a groove with a rectangular cross-section on the outer circle or the inner circle for sealing.

Y type sealing ring

It is widely used in reciprocating sealing devices.

In addition, there is a spring tension (spring energy storage) sealing ring, which is a spring added to the PTFE sealing material, there are O-shaped springs, V-shaped springs, and U-shaped springs.

YX type sealing ring for hole
