Encapsulated O-Ring

An encapsulated O-ring is a type of sealing ring that combines the chemical resistance of a PTFE (Teflon) outer layer with the elastic core of materials like silicone or FKM (Viton). The outer jacket provides excellent protection against aggressive chemicals and extreme temperatures, while the flexible core ensures a reliable, compressible seal. Encapsulated O-rings are ideal for use in harsh environments, including food processing, pharmaceuticals, and chemical applications.
