-405 RED SILICONE 70D O-RING

APG stocks the S70405, an AS568-405 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 1.975 in (50.17 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.525 in (64.14 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Silicone is specified here for excellent electrical insulating properties and flexibility that holds at very low temperatures. This material stands up to many oxidizing chemicals, dry heat, and extreme heat and cold. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. It is not the right choice where hydrocarbon fuels and oils or steam above its rated range are present.

You will find this material specified across ovens and heated equipment, pharmaceutical manufacturing, and medical devices.

S70405 ships individually. Unit weight is approximately 9.52 g and nominal inside diameter is listed as 2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
