CAUTION! Operating temperature limitations are as follows:

Materials

Santoprene® Injection molded thermoplastic elastomer with no fabric layer. Long mechanical flex life.
Excellent abrasion resistance.

Virgin PTFE Chemically inert, virtually imper vious. Very few chemicals are known to react chemically
with PTFE: molten alkali metals, turbulent liquid or gaseous fluorine and a few fluoro-chemicals such
as chlorine trifluoride or oxygen difluoride which readily liberate free fluorine at elevated temperatures.
