-324 RED SILICONE 70D FDA O-RING

This o-ring is supplied in AS568-324 red Silicone 70 Shore A measuring an inside diameter of 1.35 in (34.29 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.77 in (44.96 mm), catalogued under part number S70FDA324. It remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to extreme heat and cold, dry heat, and ozone and UV exposure. That behavior comes from the compound itself: Silicone offers flexibility that holds at very low temperatures and very good compression set resistance across its range. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). It should not be specified for service in hydrocarbon fuels and oils or concentrated acids.

The compound meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across pharmaceutical manufacturing, ovens and heated equipment, and sanitary process lines.

S70FDA324 ships individually. Unit weight is approximately 3.995 g and nominal inside diameter is listed as 1 3/8 inch. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need?
