An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Expect good resistance to nearly all process chemicals, aggressive oxidizers, and steam. PTFE-Encapsulated Viton® offers a seamless PTFE jacket over a resilient elastomer core and a non-stick sealing surface that resists fouling. Published continuous service range is -75°F (-59.4°C) to 400°F (204.4°C).
You will find this material specified across aggressive-media valves and pumps, food and beverage, and semiconductor equipment.
Stocked as TEV80207 and sold individually. Nominal inside diameter is listed as 9/16 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
