This o-ring is supplied in AS568-220 red Silicone 70 Shore A built to an inside diameter of 1.359 in (34.52 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.637 in (41.58 mm), catalogued under part number S70MD220. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Expect good resistance to extreme heat and cold, ozone and UV exposure, and dry heat. That behavior comes from the compound itself: Silicone is widely chosen for physiological inertness and low toxicity, excellent electrical insulating properties. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where abrasive dynamic service or concentrated acids are present.
This item is metal detectable for HACCP and foreign-body control programs. It sees regular use in sanitary process lines, food and beverage processing, and ovens and heated equipment.
Order part number S70MD220, sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
