This material stands up to nearly all process chemicals, wide temperature swings, and steam. PTFE-Encapsulated Silicone is widely chosen for a non-contaminating, non-stick sealing surface and strong resistance to permeation. The material carries a published service range of -75°F (-59.4°C) to 400°F (204.4°C). Exposure to installation over sharp edges or tight-radius dynamic flexing will shorten service life.

Maintenance and OEM teams specify it across pharmaceutical manufacturing, chemical processing, and food and beverage processing.

TES70432 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
