*568-153 FEP ENCAPSULATED SILICONE

Part number TES70153 is an AS568-153 red PTFE-Encapsulated Silicone 70 Shore A O-Ring measuring an inside diameter of 3.487 in (88.57 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.693 in (93.8 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against strong acids and solvents, wide temperature swings, and steam. That behavior comes from the compound itself: PTFE-Encapsulated Silicone is widely chosen for chemical inertness of PTFE with the wide temperature range of silicone and excellent recovery across extreme temperature cycling. The material carries a published service range of -75°F (-59.4°C) to 400°F (204.4°C).

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