-474 RED SILICONE 70D O-RING

The S70474 is an AS568-474 red Silicone 70 Shore A O-Ring with an inside diameter of 24.94 in (633.48 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 25.49 in (647.45 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists ozone and UV exposure, many oxidizing chemicals, and dry heat. That behavior comes from the compound itself: Silicone is widely chosen for 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). It should not be specified for service in abrasive dynamic service or steam above its rated range.

It sees regular use in electronics and electrical enclosures, food and beverage processing, and sanitary process lines.

Reference part number S70474 when ordering; the item is sold individually. Unit weight is approximately 108.2127 g and nominal inside diameter is listed as 25 inch. Check the compound against your process media, pressure and temperature before committing to a design.
