This o-ring is supplied in AS568-269 red Silicone 70 Shore A with an inside diameter of 8.734 in (221.84 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.012 in (228.9 mm), catalogued under part number S70FDA269. It creates a positive seal at flange, piston and rod interfaces without added hardware.
This material stands up to ozone and UV exposure, weathering, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone offers excellent electrical insulating properties and very good compression set resistance across its range. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where concentrated acids or hydrocarbon fuels and oils are present.
The compound meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. It sees regular use in medical devices, food and beverage processing, and sanitary process lines.
S70FDA269 ships individually. Unit weight is approximately 9.582 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
