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, […]

The Pressure Test: AFLAS® Under Extremes

Summary Why AFLAS®? Built for the Extremes In high-performance sealing environments, material selection is critical to withstand environmental stressors. System exposure to high heat, aggressive chemicals, and steam requires a material that can endure these conditions without degrading, swelling, or hardening over time.  AFLAS® offers a level of durability that general-purpose elastomers can’t match. Classified […]

AFLAS® O-Rings: Usage and Benefits

Summary AFLAS® o-rings offer excellent heat and chemical resistance, making them a superior choice for many industrial applications. AFLAS® o-rings widely use their ability to withstand harsh environments across various industries such as oil and gas, automotive, chemical processing, power generation, and pharmaceuticals. AFLAS® o-rings provide reliable sealing performance under demanding conditions, enhancing operational efficiency […]
