An O-ring is a round ring that is used as a gasket for sealing a connection. O-rings are typically constructed out of polyurethane, silicone, neoprene, nitrile rubber or fluorocarbon. These rings are commonly used in mechanical applications, such as pipe connections, and help to ensure a tight seal between two objects.
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.
