The TES70375 is an AS568-375 red PTFE-Encapsulated Silicone 70 Shore A O-Ring built to an inside diameter of 9.475 in (240.67 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.895 in (251.33 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Source specification: ORING 70 Durometer.
PTFE-Encapsulated Silicone is specified here for strong resistance to permeation and excellent recovery across extreme temperature cycling. It resists nearly all process chemicals, strong acids and solvents, and wide temperature swings. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). It is not the right choice where installation over sharp edges or tight-radius dynamic flexing are present.
Maintenance and OEM teams specify it across chemical processing, food and beverage processing, and pharmaceutical manufacturing.
Order part number TES70375, sold individually. Nominal inside diameter is listed as 9 1/2 inch. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
