O type sealing ring in oil, acid, alkali, grinding, chemical erosion and other environmental still plays a good sealing, shock absorption. Therefore, the O type sealing ring is the most widely used in the hydraulic and pneumatic transmission system.

Two, product advantage

1, suitable for a variety of sealing form: static sealing, dynamic sealing.

2, suitable for all kinds of material, size and groove have been standardized, the exchange is strong.

3, suitable for a variety of sports: rotating motion, axial reciprocating motion or combination of movement (such as a combination of rotational movement).

4, suitable for a variety of different sealing medium: oil, water, gas, chemical medium or other mixed media through the selection of appropriate rubber material and appropriate formulation, implementation of oil, water, air, gas and all kinds of chemical medium effective sealing effect. Temperature range of use (- 60 C ~ + 220), fixed use of pressure up to 1500Kg/cm2 (with the reinforcing ring and use).

5, the design is simple, compact structure, easy to install.

O - shaped ring section is very simple, and has a self sealing effect, sealing performance is reliable.

Because of the O - shaped ring itself and the installation position of the structure is extremely simple, and has formed a standard, so the installation is very easy to replace.

6, the material variety, can according to the different fluid were chosen: nitrile butadiene rubber (NBR), fluorine rubber (FKM), silicone rubber (VMQ), ethylene propylene diene rubber (EPDM) and chloroprene rubber (CR), butyl rubber (BU), polytetrafluoroethylene (PTFE), natural rubber (NR) and so on.

7, low cost.

8, the friction resistance is relatively small.
