Advantages of O-rings

Compared with other types of O-rings, O-rings have the following advantages:
--Suitable for multiple sealing forms: static sealing, dynamic sealing
Suitable for various applications. The dimensions and grooves are standardized and highly interchangeable.
--Suitable for a variety of motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating combined motion)
-Suitable for many different sealing media: oil, water, gas, chemical media or other mixed media
Through the selection of suitable rubber materials and appropriate formula design, it can effectively seal oil, water, air, gas and various chemical media. Wide temperature range (－ 60 ℃ ～ + 220 ℃), and pressure can reach 1500Kg / cm2 (fixed with reinforcement ring) when fixed use.
--Simple design, compact structure, easy assembly and disassembly
The O-ring cross-section structure is extremely simple, and it has a self-sealing effect, and the sealing performance is reliable.
Because the O-ring itself and the structure of the installation site are extremely simple and standardized, installation and replacement are easy.
-Many types 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), etc.
--low cost
-The dynamic friction resistance is relatively small
