Choosing between FKM and silicone O-rings is not simply a matter of comparing two rubber materials. Both elastomers can provide reliable sealing performance, but they respond differently to temperature, chemicals, mechanical stress, compression, pressure, and environmental exposure. FKM is widely selected for applications involving oils, fuels, hydrocarbons, elevated temperatures, and demanding industrial environments. Silicone, often identified as VMQ, is valued

When an O-ring fails, the problem is not always caused by poor manufacturing or incorrect dimensions. In many cases, the real issue starts with material selection. An O-ring may have the correct inside diameter and cross-section but still fail because the elastomer cannot withstand the temperature, chemical medium, pressure, or mechanical conditions of the application. This is particularly important when
