The most commonly used seal ring - the advantages of the ring

1) O-ring sealing performance, high working life, dynamic pressure seal working life than conventional rubber sealing products 5-10 times higher,
up to several times, under certain conditions can be sealed with the same life.
O-ring frictional resistance is small, dynamic and static friction equal, is "0" shaped rubber ring friction 1 / 2-1 / 4, can eliminate low-speed, low-pressure movement of the "crawling" phenomenon.
O-ring high wear resistance, sealing surface wear with automatic elastic compensation.
O-ring good self-lubricating performance. Can be used for oil-free seal.
O-ring structure is simple, easy to install.
O-ring working pressure: 0-30MPa; Working speed: ≤ 15m / s; Operating temperature: -55-250 degrees.
O-ring for media: hydraulic oil, gas, water, mud, crude oil, emulsion, water - ethylene glycol, acid.
O-rings are suitable for use in a variety of mechanical equipment, in the specified temperature, pressure, and different liquid and gas medium,
 in a static or moving state from the sealing effect. In the machine tools, ships, automobiles, aerospace equipment, metallurgical machinery,
chemical machinery, construction machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery,
 and various instruments, a large number of applications of various types of seals element. O-rings are mainly used for static and reciprocating seals.
For rotary motion seals, only for low speed rotary seals. O-ring is generally installed in the outer or inner circle on the rectangular cross-section
of the seal from the role. O-ring in the oil, acid, grinding, chemical erosion and other environments still play a good seal, shock absorption.
Therefore, O-ring is the hydraulic and pneumatic transmission system used in the most extensive seal.
2) O-ring compared with other types of seals, has the following advantages:
Suitable for a variety of sealed form: static seal, dynamic seal
Suitable for all kinds of materials, sizes and trenches are standardized and interchangeable
Suitable for a variety of exercise modes: rotary motion, axial reciprocating motion or combined motion (eg rotary reciprocating motion)
Suitable for a variety of different sealing media: oil, water, gas, chemical media or other mixed media
By selecting the right rubber material and the appropriate formula design, to achieve oil, water, air, gas and
a variety of chemical media effective sealing effect. Temperature range of use (- 60 ℃ ~ +220 ℃),
fixed use of the pressure up to 1500Kg / cm2 (with the reinforcement ring and use).
Simple design, compact structure, easy assembly and disassembly
O-ring cross-section structure is extremely simple, and self-sealing effect, sealing performance and reliable.
As the O-ring itself and the installation site structure is extremely simple, and has formed a standardized, so the installation and replacement are very easy.
More varieties of materials
Can be selected according to different fluids: nitrile rubber (NBR), fluorine rubber (FKM), silicone rubber (VMQ),
ethylene propylene rubber (EPDM), neoprene (CR), butyl rubber (BU), poly Tetrafluoroethylene (PTFE), natural rubber (NR), and the like
low cost
Dynamic friction resistance is relatively small
