-411 RED SILICONE 70D FDA O-RING

APG stocks the S70FDA411, an AS568-411 red Silicone 70 Shore A O-Ring measuring an inside diameter of 2.725 in (69.22 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.275 in (83.19 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Silicone is specified here for very good compression set resistance across its range and exceptionally wide service temperature range. It resists many oxidizing chemicals, dry heat, and weathering. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Exposure to abrasive dynamic service or hydrocarbon fuels and oils will shorten service life.

This item meets FDA requirements for food contact under 21 CFR 177.2600. Common environments for this compound include sanitary process lines, ovens and heated equipment, and pharmaceutical manufacturing.

Order part number S70FDA411, sold individually. Unit weight is approximately 12.876 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
