Part number S70MD414 is an AS568-414 red Silicone 70 Shore A O-Ring with an inside diameter of 3.1 in (78.74 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.65 in (92.71 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
It resists weathering, extreme heat and cold, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone delivers an exceptionally wide service temperature range and very good compression set resistance across its range. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). It should not be specified for service in abrasive dynamic service or steam above its rated range.
The compound is metal detectable for HACCP and foreign-body control programs. It sees regular use in food and beverage processing, ovens and heated equipment, and medical devices.
Stocked as S70MD414 and sold individually. Nominal inside diameter is listed as 3 1/8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
