-126 RED SILICONE 70D FDA O-RING

Part number S70FDA126 is an AS568-126 red Silicone 70 Shore A O-Ring measuring an inside diameter of 1.362 in (34.59 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.568 in (39.83 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against dry heat, many oxidizing chemicals, and weathering. That behavior comes from the compound itself: Silicone is widely chosen for physiological inertness and low toxicity, excellent electrical insulating properties. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). It should not be specified for service in hydrocarbon fuels and oils or concentrated acids.

The compound meets FDA requirements for food contact under 21 CFR 177.2600. You will find this material specified across ovens and heated equipment, pharmaceutical manufacturing, and medical devices.

Stocked as S70FDA126 and sold individually. Unit weight is approximately 0.878 g and nominal inside diameter is listed as 1 3/8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
