O ring in front of us to tell you a general situation of it, for the O ring it has its own advantages in sealing, for the O ring you also know what it is, you can understand from the following points.
1, small structure size, convenient assembly and disassembly. Because the o-ring itself and the installation part of the structure is extremely simple, and has formed a standard, so it is very easy to install and replace. Static and dynamic seals can be used, almost no leakage when used as static seals.
2, the use of a single O-ring, two-way sealing effect.
3, dynamic friction resistance is small.
4, low price. Material varieties can be selected according to different fluids: nitrile butadiene rubber (NRB), fluorine rubber (FKM), silicone rubber (VMQ), ethylene propylene rubber (EPDM), chloroprene rubber (CR), butyl rubber (BU), polytetrafluoroethylene (PTFE), natural rubber (NR) and so on.
That is to say, the O-ring structure is simple, easy to disassemble, and good sealing, moderate price, so this is one of its advantages, but also when we choose to consider the cost performance.
