It compresses into its gland to block fluid or gas migration across a joint.

It resists ozone and UV exposure, many oxidizing chemicals, and weathering. Silicone is widely chosen for excellent electrical insulating properties and very good compression set resistance across its range. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Applications involving steam above its rated range or hydrocarbon fuels and oils call for a different compound.

This o-ring is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include ovens and heated equipment, pharmaceutical manufacturing, and sanitary process lines.

This item is sold individually under part number S70MD278. Nominal inside diameter is listed as 12 inch. Check the compound against your process media, pressure and temperature before committing to a design.
