Tip: Rubber O-ring. We get some inquiries from website viewers who are looking for a natural rubber o-ring so we thought we would publish a few words about what a rubber o-ring really is. It is virtually impossible to find an o-ring that is made from natural rubber - the stuff that comes from rubber trees - today. What you will find instead is a product that is made out of a synthetic material, called an elastomer, that looks, feels and behaves like one might think natural rubber would.
O-rings are common seals used in many manufacturing industries. Because of their cost, simple production, easy installation and pressure resistance, they have found their way into a lot of common products, such as automobiles and engines. EPR o-rings work well with Skydrol and other hydraulic fluids, as well as steam, water, silicone oils, brake fluids and alcohols. 2  Deficiencies: Similar to nitrile, EPR is not perfect for a wide-range of applications due to wear and tear issues.
