Ordered as S70FDA167, this is an AS568-167 red Silicone 70 Shore A O-Ring built to an inside diameter of 6.987 in (177.47 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.193 in (182.7 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Expect good resistance to dry heat, weathering, and extreme heat and cold. That behavior comes from the compound itself: Silicone delivers flexibility that holds at very low temperatures, physiological inertness and low toxicity. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Exposure to concentrated acids or hydrocarbon fuels and oils will shorten service life.
This item meets FDA requirements for food contact under 21 CFR 177.2600. Typical settings include ovens and heated equipment, food and beverage processing, and medical devices.
