This o-ring is supplied in AS568-127 red PTFE-Encapsulated Silicone 70 Shore A with an inside diameter of 1.424 in (36.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.63 in (41.4 mm), catalogued under part number TES70127. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Source specification: ORING 70 Durometer.

The compound resists steam, wide temperature swings, and nearly all process chemicals. That behavior comes from the compound itself: PTFE-Encapsulated Silicone is valued for chemical inertness of PTFE with the wide temperature range of silicone and strong resistance to permeation. Published continuous service range is -75°F (-59.4°C) to 400°F (204.4°C).

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