Ordered as S70MD009, this is an AS568-009 red Silicone 70 Shore A O-Ring measuring an inside diameter of 0.208 in (5.28 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.348 in (8.84 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
The material holds up against dry heat, extreme heat and cold, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is known for very good compression set resistance across its range and an exceptionally wide service temperature range. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Exposure to abrasive dynamic service or steam above its rated range will shorten service life.
This item is metal detectable for HACCP and foreign-body control programs. You will find this material specified across pharmaceutical manufacturing, food and beverage processing, and sanitary process lines.
Reference part number S70MD009 when ordering; the item is sold individually. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
