-449 RED SILICONE 70D O-RING

Part number S70MD449 is an AS568-449 red Silicone 70 Shore A O-Ring measuring an inside diameter of 9.975 in (253.37 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 10.525 in (267.34 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Silicone is widely chosen for flexibility that holds at very low temperatures and an exceptionally wide service temperature range. Expect good resistance to many oxidizing chemicals, dry heat, and weathering. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Applications involving concentrated acids or steam above its rated range call for a different compound.

The compound is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include ovens and heated equipment, food and beverage processing, and medical devices.
