Compared with other types of sealing rings, the O-ring has the following advantages:
Suitable for various sealing forms: static sealing and dynamic sealing.
Suitable for various purposes of materials, with standardized dimensions and grooves, and strong interchangeability.
Suitable for various modes of motion: rotary motion, axial reciprocating motion, or combined motion (such as rotary reciprocating combined motion).
Suitable for various sealing media: oil, water, gas, chemical media, or other mixed media.
By selecting appropriate rubber materials and designing appropriate formulas, effective sealing effects on oil, water, air, gas, and various chemical media can be achieved. The temperature range is wide (-60 ℃~+220 ℃), and the pressure can reach 1500Kg/cm2 when fixed for use (combined with the reinforcing ring).
Simple design, compact structure, and convenient assembly and disassembly.
The cross-sectional structure of the O-ring is extremely simple and has a self sealing effect, ensuring reliable sealing performance.
Due to the extremely simple structure and standardized installation of the O-ring itself and its installation location, installation and replacement are very easy.
There are many types of materials.
You can choose according to different fluids: nitrile rubber (NBR), fluororubber (FKM), silicone rubber (VMQ), ethylene propylene rubber (EPDM), chloroprene rubber (CR), butyl rubber (BU), polytetrafluoroethylene (PTFE), natural rubber (NR), etc.
The dynamic friction resistance is relatively small.
