Part number S70MD234 is an AS568-234 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 2.984 in (75.79 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.262 in (82.85 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.
It resists weathering, ozone and UV exposure, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is valued for very good compression set resistance across its range and flexibility that holds at very low temperatures. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). It should not be specified for service in concentrated acids or hydrocarbon fuels and oils.
The compound is metal detectable for HACCP and foreign-body control programs. You will find this material specified across ovens and heated equipment, sanitary process lines, and electronics and electrical enclosures.
Reference part number S70MD234 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
