PTFE-Encapsulated Silicone delivers chemical inertness of PTFE with the wide temperature range of silicone and strong resistance to permeation. The material holds up against steam, nearly all process chemicals, and wide temperature swings. Continuous operating temperature is published at -75°F (-59.4°C) to 400°F (204.4°C). It should not be specified for service in tight-radius dynamic flexing or installation over sharp edges.

Common environments for this compound include food and beverage processing, chemical processing, and pharmaceutical manufacturing.

Reference part number TES70459 when ordering; the item is sold individually. Nominal inside diameter is listed as 15 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.
