-210 RED SILICONE 70D FDA O-RING

APG stocks the S70FDA210, an AS568-210 red Silicone 70 Shore A O-Ring measuring an inside diameter of 0.734 in (18.64 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.012 in (25.7 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Silicone is specified here for very good compression set resistance across its range, physiological inertness and low toxicity. The compound resists many oxidizing chemicals, extreme heat and cold, and dry heat. 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 concentrated acids.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. It sees regular use in medical devices, sanitary process lines, and pharmaceutical manufacturing.

Stocked as S70FDA210 and sold individually. Unit weight is approximately 0.954 g and nominal inside diameter is listed as 3/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
