-050 RED SILICONE 70D FDA O-RING

Part number S70FDA050 is an AS568-050 red Silicone 70 Shore A O-Ring measuring an inside diameter of 5.239 in (133.07 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 5.379 in (136.63 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against extreme heat and cold, ozone and UV exposure, and dry heat. That behavior comes from the compound itself: Silicone is valued for 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). Exposure to steam above its rated range or concentrated acids will shorten service life.

The compound meets FDA requirements for food contact under 21 CFR 177.2600. You will find this material specified across food and beverage processing, electronics and electrical enclosures, and medical devices.

This item is sold individually under part number S70FDA050. Unit weight is approximately 1.53 g and nominal inside diameter is listed as 5 1/4 inch.
