Product Specification

-
Part number S70158 is an AS568-158 red Silicone 70 Shore A O-Ring measuring an inside diameter of 4.737 in (120.32 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 4.943 in (125.55 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Silicone is valued for very good compression set resistance across its range and an exceptionally wide service temperature range. Expect good resistance to dry heat, ozone and UV exposure, and many oxidizing chemicals. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Applications involving abrasive dynamic service or steam above its rated range call for a different compound.

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

Reference part number S70158 when ordering; the item is sold individually. Unit weight is approximately 2.973 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
