Advantages of O-rings

Compared with other types of sealing rings, O-rings have the following advantages:
--Suitable for various sealing forms: static sealing, dynamic sealing
Suitable for various materials, the size and grooves are standardized, and the interchangeability is strong
--Suitable for various modes of movement: rotational movement, axial reciprocating movement or combined movement (such as rotational reciprocating combined movement)
--Suitable for a variety of different sealing media: oil, water, gas, chemical media or other mixed media
By selecting suitable rubber materials and appropriate formula design, effective sealing for oil, water, air, gas and various chemical media can be achieved. The temperature range of use is wide (-60 ℃ ~ + 220 ℃), and the pressure can reach 1500Kg/cm2 when used fixedly (used with reinforcement rings).
--Simple design, compact structure, easy installation and disassembly
The cross-sectional structure of the O-ring is extremely simple, and it has a self-sealing effect and reliable sealing performance.
Since the O-ring itself and the installation part structure are extremely simple and standardized, installation and replacement are very easy.
--Various materials
Can be selected 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.
--Low cost
--Relatively small dynamic friction resistance
