Viton® (FKM) is known for excellent resistance to compression set and permeation, very low compression set at elevated temperature. The material holds up against aromatic hydrocarbons, chlorinated solvents, and many acids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with ketones and esters or low-molecular-weight organic acids.
Typical settings include high-temperature process equipment, automotive fuel systems, and oil and gas.
QV70265 ships individually. Nominal inside diameter is listed as 7 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
