-430 RED SILICONE 70D O-RING

The S70430 is an AS568-430 red Silicone 70 Shore A O-Ring measuring an inside diameter of 5.1 in (129.54 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.65 in (143.51 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists weathering, dry heat, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is specified for physiological inertness and low toxicity, 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).

You will find this material specified across electronics and electrical enclosures, pharmaceutical manufacturing, and ovens and heated equipment.

Stocked as S70430 and sold individually. Unit weight is approximately 22.35 g. 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.
