-345 RED SILICONE 70D FDA O-RING

Part number S70FDA345 is an AS568-345 red Silicone 70 Shore A O-Ring with an inside diameter of 3.975 in (100.97 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.395 in (111.63 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists many oxidizing chemicals, ozone and UV exposure, and extreme heat and cold. Silicone is specified for very good compression set resistance across its range and excellent electrical insulating properties. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Exposure to concentrated acids or abrasive dynamic service will shorten service life.

This o-ring meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. Typical settings include food and beverage processing, pharmaceutical manufacturing, and medical devices.
