-204 RED SILICONE 70D O-RING

S70MD204 is an AS568-204 red Silicone 70 Shore A O-Ring measuring an inside diameter of 0.359 in (9.12 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.637 in (16.18 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against extreme heat and cold, weathering, and dry heat. Silicone is known for excellent electrical insulating properties and flexibility that holds at very low temperatures. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). It is not the right choice where steam above its rated range or concentrated acids are present.

The compound is metal detectable for HACCP and foreign-body control programs. It sees regular use in electronics and electrical enclosures, sanitary process lines, and food and beverage processing.

Stocked as S70MD204 and sold individually. Nominal inside diameter is listed as 3/8 inch.
