Advantages of O-ring Mechanical Seals

Compared with other types of sealing rings, O-rings have the following advantages:

--Suitable for various sealing forms: static sealing, dynamic sealing

Materials suitable for various uses, sizes and grooves have been standardized, and are highly interchangeable

--Suitable for a variety of motion modes: rotational motion, axial reciprocating motion or combined motion (such as rotational reciprocating combined motion)

--Suitable for many different sealing media: oil, water, gas, chemical media or other mixed media

By selecting appropriate rubber materials and appropriate formula design, effective sealing effects on oil, water, air, gas and various chemical media can be achieved. It has a wide temperature range (-60 ℃ ~ + 220 ℃), and the pressure can reach 1500Kg/cm2 when used in a fixed manner (used together with reinforcing rings).

--Simple design, compact structure, easy assembly and disassembly

The O-ring cross-sectional structure is extremely simple, has a self-sealing effect, and has reliable sealing performance.

Since the structure of the O-ring itself and the installation part are extremely simple and standardized, installation and replacement are very easy.

--Many types of materials

You can choose according to different fluids: nitrile rubber (NBR), fluorine rubber (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 resistance is relatively small
