Key Properties:
O-rings offer excellent compression resistance, weather/ozone resistance, abrasion resistance, and chemical/oil compatibility while maintaining stable performance across wide temperature ranges.
Critical Design Factors:
Proper design prevents premature failure. While O-rings can withstand high pressure when correctly designed, common failure modes in extreme conditions include permanent deformation, gap extrusion, and twisting during operation. Correct installation and material selection are essential for optimal sealing performance.
