An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Silicone is valued for very good compression set resistance across its range and excellent electrical insulating properties. The compound resists many oxidizing chemicals, ozone and UV exposure, and extreme heat and cold. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with hydrocarbon fuels and oils or abrasive dynamic service.
It sees regular use in electronics and electrical enclosures, medical devices, and sanitary process lines.
Order part number S70121, sold individually. Unit weight is approximately 0.696 g and nominal inside diameter is listed as 1 1/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
