O-Ring Materials, Applications, and Selection

Summary Introduction An o-ring is an elastomeric ring with a round cross-section that forms a seal by squeezing and applying pressure. That sealing mechanism depends on the elastomer returning toward its original shape after deformation (elastic recovery) and maintaining contact pressure against the gland surfaces over time. Because elastomers respond differently to heat, cold, fluids, […]

AFLAS® vs Viton® vs FFKM O-Ring Performance

Summary Introduction AFLAS® (FEPM/TFE-P), Viton® (FKM), and FFKM are often grouped together under the “fluoropolymer o-ring” label. Despite this shared classification, each material responds differently to environmental exposure. Real-world performance depends on how an elastomer ages under sustained operating conditions. Steam, alkaline media, solvents, and elevated temperatures introduce distinct degradation mechanisms that influence elasticity, hardness, […]

Quality Sealing in Semiconductor Vacuums

Summary Vacuum Systems Are Essential in Semiconductor Manufacturing Chip manufacturers rely on vacuum systems to ensure the highest precision and cleanliness. These systems create the controlled environment required for essential manufacturing processes by removing air and unwanted gas. However, maintaining a stable vacuum system can be complex. Leaks, material outgassing, and seal degradation can introduce […]
