O-ring advantage:

O-ring seals compared with other types, has the following advantages:

- For a variety of seal forms: static seals, dynamic seals

- Suitable for various uses materials, dimensions and grooves have been standardized, interchangeable

- For a variety of motion: rotation, axial reciprocating movement or combination of movements (such as rotating the shuttle combined motion)

- Suitable for a variety of different sealing medium: oil, water, gas, chemical, mixed media or other media

By appropriate choice of rubber materials and appropriate formulations designed to realize the oil, water, air, gas and chemical media and effective seal. Wide temperature range (- 60 ℃ ~ + 220 ℃), the use of fixed pressure up to 1500Kg / cm2 (and reinforcing ring and use). O-ring

- Simple design, compact, easy assembly and disassembly

O-ring cross-sectional structure is extremely simple, and there is self-sealing, reliable sealing performance.

 Since the O-ring and install parts of the structure itself is extremely simple and has become standardized, so installation is very easy to replace.

- Material Variety

Can be selected depending on the fluid: There are nitrile rubber (NBR), Viton (FKM), silicone rubber (VMQ), ethylene-propylene rubber (EPDM), chloroprene rubber (CR), butyl rubber (BU), poly tetrafluoroethylene (PTFE), natural rubber (NR), etc.

--low cost 

- Dynamic friction is relatively small
