568-436 FEP ENCAPSULATED SILICONE

Part number TES70436 is an AS568-436 red PTFE-Encapsulated Silicone 70 Shore A O-Ring measuring an inside diameter of 5.85 in (148.59 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 6.4 in (162.56 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint. This item is further identified as ORING 70 Durometer.

PTFE-Encapsulated Silicone is specified here for strong resistance to permeation and chemical inertness of PTFE with the wide temperature range of silicone. The material holds up against nearly all process chemicals, wide temperature swings, and strong acids and solvents. Continuous operating temperature is published at -75°F (-59.4°C) to 400°F (204.4°C). Applications involving tight-radius dynamic flexing or installation over sharp edges call for a different compound.

Maintenance and OEM teams specify it across food and beverage processing, cryogenic and high-temperature equipment, and pharmaceutical manufacturing.

This item is sold individually under part number TES70436. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
