-328 RED SILICONE 70D FDA O-RING

This o-ring is supplied in AS568-328 red Silicone 70 Shore A measuring an inside diameter of 1.85 in (46.99 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.27 in (57.66 mm), catalogued under part number S70FDA328. It compresses into its gland to block fluid or gas migration across a joint.

As a material, Silicone is known for very good compression set resistance across its range, physiological inertness and low toxicity. The compound resists dry heat, ozone and UV exposure, and weathering. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Applications involving hydrocarbon fuels and oils or abrasive dynamic service call for a different compound.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across sanitary process lines, ovens and heated equipment, and electronics and electrical enclosures.

Reference part number S70FDA328 when ordering; the item is sold individually. Unit weight is approximately 5.198 g and nominal inside diameter is listed as 1 7/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
