PTFE-Encapsulated Silicone is specified here for non-contaminating, non-stick sealing surface and strong resistance to permeation. The compound resists strong acids and solvents, nearly all process chemicals, and steam. 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 TES70463. Nominal inside diameter is listed as 17 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
