Ordered as S70FDA455, this is an AS568-455 red Silicone 70 Shore A O-Ring with an inside diameter of 12.975 in (329.57 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 13.525 in (343.54 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Expect good resistance to dry heat, extreme heat and cold, and weathering. That behavior comes from the compound itself: Silicone offers an exceptionally wide service temperature range and flexibility that holds at very low temperatures. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Applications involving abrasive dynamic service or hydrocarbon fuels and oils call for a different compound.
The compound meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include ovens and heated equipment, medical devices, and sanitary process lines.
This item is sold individually under part number S70FDA455. Unit weight is approximately 55.56 g and nominal inside diameter is listed as 13 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
