This o-ring is supplied in AS568-263 red Silicone 70 Shore A with an inside diameter of 7.234 in (183.74 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 7.512 in (190.8 mm), catalogued under part number S70MD263. It remains the most cost-effective sealing element available for pressurized assemblies.
Expect good resistance to many oxidizing chemicals, dry heat, and ozone and UV exposure. That behavior comes from the compound itself: Silicone is widely chosen for flexibility that holds at very low temperatures, physiological inertness and low toxicity. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where steam above its rated range or abrasive dynamic service are present.
This item is metal detectable for HACCP and foreign-body control programs. Typical settings include ovens and heated equipment, electronics and electrical enclosures, and pharmaceutical manufacturing.
S70MD263 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
