-240 RED SILICONE 70D FDA O-RING

This o-ring is supplied in AS568-240 red Silicone 70 Shore A built to an inside diameter of 3.734 in (94.84 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.012 in (101.9 mm), catalogued under part number S70FDA240. It compresses into its gland to block fluid or gas migration across a joint.

Silicone is widely chosen for an exceptionally wide service temperature range and flexibility that holds at very low temperatures. The compound resists extreme heat and cold, weathering, and dry heat. 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.
