This material stands up to strong acids and solvents, wide temperature swings, and nearly all process chemicals. That behavior comes from the compound itself: PTFE-Encapsulated Silicone is known for excellent recovery across extreme temperature cycling and a non-contaminating, non-stick sealing surface. The material carries a published service range of -75°F (-59.4°C) to 400°F (204.4°C). Verify compatibility before use with installation over sharp edges or tight-radius dynamic flexing.

It sees regular use in food and beverage processing, pharmaceutical manufacturing, and chemical processing.

This item is sold individually under part number TES70148. Check the compound against your process media, pressure and temperature before committing to a design.
