Compared with other types of seals, O-rings have the following advantages:
1. Suitable for a variety of sealing forms: static sealing, dynamic sealing
2. Suitable for all kinds of materials, the size and groove have been standardized, and the interchangeability is strong
3. Suitable for a variety of motion methods: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating combined motion)
4. 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, an effective sealing effect 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 (used with the reinforcing ring) in fixed use.
5. Simple design, compact structure, convenient assembly and disassembly
The cross-sectional structure of the O-ring is extremely simple, and has a self-sealing effect, and the sealing performance is reliable.
Since the structure of the O-ring itself and the installation part are extremely simple and standardized, the installation and replacement are very easy.
6. Variety of materials
You can choose according to different fluids: (NBR), fluorine rubber (FKM), silicone rubber (VMQ), ethylene propylene rubber (EPDM), chloroprene rubber (CR), butyl rubber (BU), polytetrafluoroethylene (PTFE), natural rubber (NR), etc.
7. Low cost
8. The dynamic friction resistance is relatively small
