-156 RED SILICONE 70D FDA O-RING

This o-ring is supplied in AS568-156 red Silicone 70 Shore A measuring an inside diameter of 4.237 in (107.62 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 4.443 in (112.85 mm), catalogued under part number S70FDA156. It remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Silicone delivers flexibility that holds at very low temperatures and very good compression set resistance across its range. The material holds up against ozone and UV exposure, dry heat, and extreme heat and cold. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Exposure to steam above its rated range or abrasive dynamic service will shorten service life.

The compound meets FDA requirements for food contact under 21 CFR 177.2600. It sees regular use in medical devices, electronics and electrical enclosures, and ovens and heated equipment.

Stocked as S70FDA156 and sold individually. Unit weight is approximately 2.552 g and nominal inside diameter is listed as 4 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
