-407 RED SILICONE 70D FDA O-RING

APG stocks the S70FDA407, an AS568-407 red Silicone 70 Shore A O-Ring built to an inside diameter of 2.225 in (56.52 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.775 in (70.49 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Silicone is widely chosen for very good compression set resistance across its range, physiological inertness and low toxicity. It resists extreme heat and cold, many oxidizing chemicals, and ozone and UV exposure. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where steam above its rated range or abrasive dynamic service are present.

This item meets FDA requirements for food contact under 21 CFR 177.2600. Typical settings include electronics and electrical enclosures, pharmaceutical manufacturing, and sanitary process lines.
