-364 RED SILICONE 70D FDA O-RING

APG stocks the S70FDA364, an AS568-364 red Silicone 70 Shore A O-Ring with an inside diameter of 6.725 in (170.82 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.145 in (181.48 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists dry heat, extreme heat and cold, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is specified for physiological inertness and low toxicity, excellent electrical insulating properties. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Applications involving hydrocarbon fuels and oils or abrasive dynamic service call for a different compound.

This item meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across pharmaceutical manufacturing, medical devices, and sanitary process lines.

Stocked as S70FDA364 and sold individually. Unit weight is approximately 17.279 g and nominal inside diameter is listed as 6 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
