-246 RED SILICONE 70D FDA O-RING

The S70FDA246 is an AS568-246 red Silicone 70 Shore A O-Ring built to an inside diameter of 4.484 in (113.89 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.762 in (120.95 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Silicone is specified here for exceptionally wide service temperature range, physiological inertness and low toxicity. The material holds up against ozone and UV exposure, extreme heat and cold, and many oxidizing chemicals. Continuous operating temperature is published at -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.
