This o-ring is supplied in AS568-330 black PTFE-Encapsulated Viton® 90 Shore A built to an inside diameter of 2.1 in (53.34 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.52 in (64.01 mm), catalogued under part number TEV80330. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
It resists nearly all process chemicals, steam, and strong acids and solvents. That behavior comes from the compound itself: PTFE-Encapsulated Viton® offers excellent resistance to permeation and contamination, a seamless PTFE jacket over a resilient elastomer core. Rated temperature range runs from -75°F (-59.4°C) to 400°F (204.4°C) in continuous service.
You will find this material specified across food and beverage, semiconductor equipment, and aggressive-media valves and pumps.
This item is sold individually under part number TEV80330. Nominal inside diameter is listed as 2 1/8 inch. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
