-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, is metal detectable for HACCP and foreign-body control programs. 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.
