Product Specification

-
Ordered as S70MD321, this is an AS568-321 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 1.162 in (29.51 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.582 in (40.18 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to many oxidizing chemicals, dry heat, and weathering. That behavior comes from the compound itself: Silicone is specified for flexibility that holds at very low temperatures, physiological inertness and low toxicity. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). It should not be specified for service in hydrocarbon fuels and oils or steam above its rated range.

The compound is metal detectable for HACCP and foreign-body control programs. You will find this material specified across pharmaceutical manufacturing, ovens and heated equipment, and medical devices.

This item is sold individually under part number S70MD321. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
