Flowserve 568344AF AFLAS O-Ring Seal

The Flowserve 568344AF is a high-performance AFLAS O-ring seal designed for demanding industrial applications requiring superior chemical resistance and thermal stability. Manufactured by Flowserve's Fluid Sealing Division, this O-ring is made from AFLAS, a tetrafluoroethylene-propylene (TFE/P) copolymer elastomer that excels in environments with aggressive chemicals, steam, and high temperatures. It is commonly used in oil and gas, chemical processing, and pharmaceutical industries for sealing valves, pumps, and piping systems. Key features include excellent resistance to acids, bases, amines, and hydrocarbons, with a broad temperature range from -10°C to 230°C (14°F to 446°F). Advantages over standard Viton or EPDM O-rings include better performance in sour gas and amine-rich environments, reducing downtime and maintenance costs. However, it may have higher material costs and slightly lower flexibility at very low temperatures compared to silicone alternatives. This unit is new, unit-packed, and appears unused based on packaging and visual inspection. The part follows AS568 sizing standards, specifically size 344, making it compatible with standard grooves. Batch #0080148956 and 'Same As: 1Q11' are noted on the label. For detailed specs, refer to Flowserve's AFLAS material data sheets. Estimated market price for new units ranges from $15-30 USD based on comparable online listings from industrial suppliers like Grainger and McMaster-Carr.
