568-219 FEP ENCAPSULATED SILICONE

Part number TES70219 is an AS568-219 red PTFE-Encapsulated Silicone 70 Shore A O-Ring with an inside diameter of 1.296 in (32.92 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.574 in (39.98 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint. Additional detail on this item: ORING 70 Durometer.

It resists strong acids and solvents, wide temperature swings, and steam. That behavior comes from the compound itself: PTFE-Encapsulated Silicone is specified for excellent recovery across extreme temperature cycling and strong resistance to permeation. Published continuous service range is -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.

Typical settings include food and beverage processing, chemical processing, and cryogenic and high-temperature equipment.

This item is sold individually under part number TES70219. Nominal inside diameter is listed as 1 5/16 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
