          FEP Encapsulated Silicone O-Rings,PFA Encapsulated Silicone O-Rings


          Silicone O-Rings encapsulated with FEP or PFA are designed to address the growing problem of sealing in the most hostile chemical and temperature environments. It combines the best qualities of two materials, FEP or PFA on the outside with its chemical inertness and an elastomer on the inside for resilience. This unique combination forms a highly effective, long lasting seal for the most demanding applications.
          Encapsulated O-Rings are available in over 60 standard cross-section sizes from .063" (1.60mm) to 1-1/4" (31.75mm). StandardEncapsulated O-Ringsare comprised of FEP over silicone can be used in temperatures from -75° to +400°F (-60° to +205°C) depending upon the choice of elastomer core.

          For high temperature applications to 500°F (260°C).

          PFA has higher mechanical strength than FEP at elevated temperatures and has excellent crack and stress resistance.
