The S70018 is an AS568-018 red Silicone 70 Shore A O-Ring built to an inside diameter of 0.739 in (18.77 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.879 in (22.33 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Silicone is specified here for very good compression set resistance across its range and exceptionally wide service temperature range. It resists many oxidizing chemicals, ozone and UV exposure, and dry heat. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Exposure to abrasive dynamic service or hydrocarbon fuels and oils will shorten service life.
Common environments for this compound include pharmaceutical manufacturing, food and beverage processing, and electronics and electrical enclosures.
Reference part number S70018 when ordering; the item is sold individually. Unit weight is approximately 0.23 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. 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.
