According to seal be used different materials, nature produces different classification:
1. The high temperature seals
2. The high pressure seals
3. The corrosion-resistant seals
4. wear-resistant seals
Seal is mainly used for oil and water repellent preservative gas seal to prevent leakage:
IDI-ring, UN-ring, UHS-ring, OSI-ring, UPH-ring, YX-ring, YA-ring, QY-ring, KY-ring, O-ring, rectangular ring, star-ring, L-type collar, DKB-type dust ring, DKI-type dust ring, DKBI type dust ring, AF-type dust ring, DH-type dust ring, DHS-type dust ring, Lei-ring, drum circle, hill-ring port seals. Viton seals. fluorine rubber seals silicone rubber seals. silicone seals. high temperature seals .o .o-ring-ring seal coating circle, including fluorine seal ring .v .y ring. .kdas star ring combination rings, nok.nak. coated metal gaskets, PTFE seals. seal rubber seals, plastic seals editor the role of the various types of seal segment
V-ring
Is an axially acting elastic rubber ring is used as non-pressure shaft seal. Sealing lip activity and better adaptability to compensate for greater tolerance and angle of deviation, to prevent internal leakage of grease or oil out, but also to prevent splashing water or dust outside intrusion.
O-ring
Mainly used for static seals and reciprocating seals. Seal for rotary motion, the only low-speed rotary sealing device.
Rectangular ring
Usually mounted on the outer or inner circular cross-section from the seal rectangular groove.
Y-ring
Widely used in reciprocating dynamic sealing device.
In addition, the spring tension (spring accumulator) ring, is to join a spring among PTFE sealing materials, O-spring, V-shaped spring, U-shaped spring.

※ ring sealing performance, high working life, dynamic pressure seal 5-10 times working life than conventional rubber seal products, up to several times, and under certain conditions can seal matrix with life.
※ seal friction is small, dynamic and static friction equal to "0" shaped rubber ring friction 1 / 2-1 / 4, to eliminate low-speed, low pressure campaign "crawling" phenomenon.
※ ring high wear resistance, abrasion after sealing surface elasticity with automatic compensation function.
※ ring good self-lubricating properties. It can be used for oil-free seal.
※ ring structure is simple, easy to install.
※ ring Working pressure: 0 to 300MPa; Working speed: ≤15m / s; Operating temperature: -55-250 ℃.
※ seals Applicable medium: hydraulic oil, gas, water, mud, oil, emulsion, water - glycol, acids, alkalis, chemicals and the like.
