The S70MD048 is an AS568-048 red Silicone 70 Shore A O-Ring built to an inside diameter of 4.739 in (120.37 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 4.879 in (123.93 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The compound resists weathering, dry heat, and extreme heat and cold. That behavior comes from the compound itself: Silicone delivers physiological inertness and low toxicity, excellent electrical insulating properties. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Applications involving concentrated acids or hydrocarbon fuels and oils call for a different compound.
This item is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include ovens and heated equipment, sanitary process lines, and electronics and electrical enclosures.
Order part number S70MD048, sold individually. Nominal inside diameter is listed as 4 3/4 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.
