what is o ring?

The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.
O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable and have simple mounting requirements. They can seal tens of megapascals (thousands of psi) of pressure.

Over 2000 different size o ring in our stock, we can design and manufacture complete sets of rubber parts based on customer's requirements, any specification is welcome according to your requirements.
