Rubber O Ring Manufacturers

Rubber O-rings are mechanical seals that are manufactured from natural rubber, an elastomer that is derived from latex. O-rings made from rubber are generally not resistant to sunlight and ozone, but compatible with vegetable oils, animal oils, and most oxidizing chemicals. These O-rings are also compatible with ketones and alcohol. However, with the advent of superior synthetic elastomers that feature improved resistance to temperatures as well as chemicals, natural rubber O rings are increasingly being replaced by synthetic elastomer O-rings made from materials such as Buna-N and silicone rubber.

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.
