-444 RED SILICONE 70D FDA O-RING

APG stocks the S70FDA444, an AS568-444 red Silicone 70 Shore A O-Ring measuring an inside diameter of 7.725 in (196.22 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 8.275 in (210.19 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists ozone and UV exposure, extreme heat and cold, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is valued for excellent electrical insulating properties and flexibility that holds at very low temperatures. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with abrasive dynamic service or steam above its rated range.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. Typical settings include medical devices, food and beverage processing, and electronics and electrical enclosures.

Stocked as S70FDA444 and sold individually. Unit weight is approximately 33.96 g. Review your operating media and conditions against this specification before installation.
