-320 RED SILICONE 70D O-RING

Ordered as S70MD320, this is an AS568-320 red Silicone 70 Shore A O-Ring built to an inside diameter of 1.1 in (27.94 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.52 in (38.61 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to many oxidizing chemicals, weathering, and ozone and UV exposure. Silicone is valued for very good compression set resistance across its range and excellent electrical insulating properties. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Applications involving hydrocarbon fuels and oils or concentrated acids call for a different compound.

This o-ring is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across sanitary process lines, electronics and electrical enclosures, and medical devices.

Stocked as S70MD320 and sold individually. Nominal inside diameter is listed as 1 1/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
