-121 RED SILICONE 70D O-RING

This o-ring is supplied in AS568-121 red Silicone 70 Shore A built to an inside diameter of 1.049 in (26.64 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.255 in (31.88 mm), catalogued under part number S70MD121. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to many oxidizing chemicals, dry heat, and ozone and UV exposure. That behavior comes from the compound itself: Silicone delivers excellent electrical insulating properties, physiological inertness and low toxicity. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with hydrocarbon fuels and oils or steam above its rated range.

The compound is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across sanitary process lines, medical devices, and pharmaceutical manufacturing.

This item is sold individually under part number S70MD121. Application requirements vary, so validate compatibility with your process conditions prior to installation.
