Common Materials for Rotary Seals
Ensuring Components Work Smoothly and Efficiently
Several materials are commonly used for rotary seals in automotive components due to properties that enhance sealing effectiveness and durability. The choice of material will depend on the type of fluid being sealed, temperature, pressure, speed, and the specific application. Some typical materials include nitrile rubber, fluorocarbon rubber (FKM/Viton), PTFE, silicone rubber, EPDM, and hydrogenated nitrile rubber. These materials offer sealing effectiveness, durability, chemical resistance, temperature resistance, low friction, and environmental compliance.
