PTFE-Encapsulated Silicone is specified here for strong resistance to permeation and chemical inertness of PTFE with the wide temperature range of silicone. The compound resists nearly all process chemicals, steam, and strong acids and solvents. The material carries a published service range of -75°F (-59.4°C) to 400°F (204.4°C). It is not the right choice where tight-radius dynamic flexing or installation over sharp edges are present.

Maintenance and OEM teams specify it across cryogenic and high-temperature equipment, chemical processing, and pharmaceutical manufacturing.

This item is sold individually under part number TES70326. Nominal inside diameter is listed as 1 5/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
