-316 RED SILICONE 70D O-RING

Part number S70316 is an AS568-316 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 0.85 in (21.59 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.27 in (32.26 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to many oxidizing chemicals, weathering, and ozone and UV exposure. That behavior comes from the compound itself: Silicone is known for very good compression set resistance across its range and flexibility that holds at very low temperatures. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Applications involving abrasive dynamic service or concentrated acids call for a different compound.

It sees regular use in medical devices, food and beverage processing, and sanitary process lines.
