Ordered as S70MD418, this is an AS568-418 red Silicone 70 Shore A O-Ring with an inside diameter of 3.6 in (91.44 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.15 in (105.41 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Silicone is specified for excellent electrical insulating properties and flexibility that holds at very low temperatures. The compound resists weathering, extreme heat and cold, and many oxidizing chemicals. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Applications involving steam above its rated range or abrasive dynamic service call for a different compound.
This item is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across pharmaceutical manufacturing, sanitary process lines, and ovens and heated equipment.
S70MD418 ships individually. 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.
