Part number S70MD236 is an AS568-236 red Silicone 70 Shore A O-Ring built to an inside diameter of 3.234 in (82.14 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.512 in (89.2 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.
Silicone is specified here for physiological inertness and low toxicity, flexibility that holds at very low temperatures. It resists weathering, dry heat, and many oxidizing chemicals. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Exposure to steam above its rated range or hydrocarbon fuels and oils will shorten service life.
This o-ring is metal detectable for HACCP and foreign-body control programs. You will find this material specified across sanitary process lines, food and beverage processing, and medical devices.
