O-rings are widely used in life, such as home appliances, automobiles, fire-fighting pharmaceuticals, etc. Especially compared with other forms of sealing rings, it has more advantages. Let's take a look at it below.
Compared with other types of sealing rings, O-rings have the following advantages:
1. Suitable for a variety of sealing forms: static sealing, dynamic sealing, suitable for various materials, dimensions and grooves have been standardized, with strong interchangeability.
2. Suitable for a variety of motion modes: rotary motion, axial reciprocating motion, or combined motion (such as rotary reciprocating combined motion).
3. Suitable for a variety of different sealing media: oil, water, gas, chemical media, or other mixed media. Through the selection of appropriate rubber materials and appropriate formulation design, the effective sealing effect on oil, water, air, gas, and various chemical media can be achieved. The temperature range is wide (-60 degree plus 220 degree ), and the pressure can reach 1500Kg/cm2 in fixed use (used together with the reinforcing ring).
4. Simple design, compact structure, convenient assembly, and disassembly. The cross-sectional structure of the O-ring seal is extremely simple, and it has a self-sealing function and reliable sealing performance. Since the O-ring itself and the structure of the installation site are extremely simple and standardized, it is very easy to install and replace.
5. There are many kinds of materials. Can be selected according to different fluids: nitrile butadiene rubber (NBR), fluorine rubber (FKM), silicone rubber (VMQ), ethylene-propylene rubber (EPDM), neoprene rubber (CR), butyl rubber (BU), poly Tetrafluoroethylene (PTFE), Natural Rubber (NR), etc.
6. Low cost
7. The dynamic friction resistance is relatively small
Choosing the right sealing ring is a key step. O-rings can adapt to most environments and have great advantages themselves.
