-169 RED SILICONE 70D FDA O-RING

This o-ring is supplied in AS568-169 red Silicone 70 Shore A supplied with an inside diameter of 7.487 in (190.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.693 in (195.4 mm), catalogued under part number S70FDA169. It creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists ozone and UV exposure, weathering, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is widely chosen for flexibility that holds at very low temperatures and an exceptionally wide service temperature range. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Applications involving concentrated acids or steam above its rated range call for a different compound.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. You will find this material specified across sanitary process lines, food and beverage processing, and medical devices.

This item is sold individually under part number S70FDA169. Unit weight is approximately 4.73 g and nominal inside diameter is listed as 7 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
