Part number S70FDA259 is an AS568-259 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 6.234 in (158.34 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.512 in (165.4 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
The material holds up against ozone and UV exposure, many oxidizing chemicals, and weathering. Silicone is widely chosen for very good compression set resistance across its range and an exceptionally wide service temperature range. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. It should not be specified for service in abrasive dynamic service or steam above its rated range.
This item meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across sanitary process lines, ovens and heated equipment, and food and beverage processing.
S70FDA259 ships individually. Unit weight is approximately 6.936 g and nominal inside diameter is listed as 6 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. 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.
