-045 RED SILICONE 70D FDA O-RING

S70FDA045 is an AS568-045 red Silicone 70 Shore A O-Ring built to an inside diameter of 3.989 in (101.32 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 4.129 in (104.88 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Silicone is widely chosen for very good compression set resistance across its range and excellent electrical insulating properties. The compound resists ozone and UV exposure, weathering, and dry heat. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Exposure to hydrocarbon fuels and oils or concentrated acids will shorten service life.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. It sees regular use in medical devices, food and beverage processing, and electronics and electrical enclosures.

Reference part number S70FDA045 when ordering; the item is sold individually. Unit weight is approximately 1.19 g and nominal inside diameter is listed as 4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
