Rubber sealing ring is a common sealing element in seals. The classification of rubber sealing ring is usually based on its main materials, characteristics and forms of movement. The rubber sealing ring manufacturers will introduce the classification method of rubber sealing ring.

According to the rubber sealing ring movement form to classify: usually there are two kinds of movement form, namely dynamic seal and static seal. Static sealing refers to sealing on two stationary surfaces. The most widely used O-ring is mainly used in static seal, followed by gasket seal. In the dynamic seal, according to whether there is contact between the seal ring and its relative moving parts, it can be divided into contact seal and non-contact seal. Among them, the rubber sealing ring is a contact sealing way. Usually in the dynamic seal, the common forms of rubber seal ring are rotary shaft lip seal ring and reciprocating motion seal ring.

According to the rubber seal ring material classification: through different materials to divide different seal ring, usually use nitrile rubber seal ring. Other common materials such as silicone rubber sealing ring, fluororubber sealing ring, etc.

According to the characteristics of rubber sealing ring classification: this classification is mainly combined with the working conditions and materials of the sealing ring. It can be divided into high temperature resistant rubber seal ring, low temperature resistant rubber seal ring, high pressure resistant rubber seal ring, wear-resistant rubber seal ring, corrosion-resistant rubber seal ring, etc.
