APG stocks the S70155, an AS568-155 red Silicone 70 Shore A O-Ring with an inside diameter of 3.987 in (101.27 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 4.193 in (106.5 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
As a material, Silicone is valued for excellent electrical insulating properties and an exceptionally wide service temperature range. The compound resists weathering, many oxidizing chemicals, and ozone and UV exposure. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Exposure to abrasive dynamic service or hydrocarbon fuels and oils will shorten service life.
It sees regular use in food and beverage processing, sanitary process lines, and medical devices.
S70155 ships individually. Unit weight is approximately 2.55 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
