.770" X .870 OVAL

Part number 0286750X875 is a red Silicone 70 Shore A oval profile O-Ring Cord Stock built to a cross section of 0.875 in (22.23 mm). An o-ring cord stock lets you fabricate a custom-size seal on site by cutting and splicing to the required circumference.

It resists dry heat, many oxidizing chemicals, and ozone and UV exposure. That behavior comes from the compound itself: Silicone offers flexibility that holds at very low temperatures and very good compression set resistance across its range. It should not be specified for service in concentrated acids or hydrocarbon fuels and oils.

It sees regular use in pharmaceutical manufacturing, sanitary process lines, and medical devices.
