-244 RED SILICONE 70D FDA O-RING

Part number S70FDA244 is an AS568-244 red Silicone 70 Shore A O-Ring measuring an inside diameter of 4.234 in (107.54 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.512 in (114.6 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists dry heat, many oxidizing chemicals, and weathering. Silicone offers very good compression set resistance across its range and flexibility that holds at very low temperatures. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Applications involving steam above its rated range or hydrocarbon fuels and oils call for a different compound.

This item 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.

This item is sold individually under part number S70FDA244. Unit weight is approximately 4.807 g and nominal inside diameter is listed as 4 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
