S70MD336 is an AS568-336 red Silicone 70 Shore A O-Ring with an inside diameter of 2.85 in (72.39 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.27 in (83.06 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The compound resists dry heat, ozone and UV exposure, and many oxidizing chemicals. Silicone delivers physiological inertness and low toxicity, very good compression set resistance across its range. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service.
This o-ring is metal detectable for HACCP and foreign-body control programs. You will find this material specified across electronics and electrical enclosures, pharmaceutical manufacturing, and sanitary process lines.
Order part number S70MD336, sold individually. Nominal inside diameter is listed as 2 7/8 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
