By combining the energizing properties of Silicone or Viton® with the chemical resistance of FEP / PFA Teflon® flouropolymers, you get an o-ring capable of handeling extream applications wwith out the extream price of Kalrez®.

As a rule, Silicone cores are better for low temperature applications. Viton® has a lower compression set figure and is recommended for applications to 400 F (constant).
