3MM CS X 6MM ID RED SILICONE 70D

APG stocks the SFDA3X6, a red Silicone 70 Shore A O-Ring with an inside diameter of 6 mm (0.236 in), a cross section of 3 mm (0.118 in), and an outside diameter of 12 mm (0.47 in). An o-ring compresses into its gland to block fluid or gas migration across a joint. Source specification: FDA Compliant TO 21CFR Sec 177-2600, Metric O-RING.

The material holds up against ozone and UV exposure, many oxidizing chemicals, and extreme heat and cold. That behavior comes from the compound itself: Silicone is specified for an exceptionally wide service temperature range and very good compression set resistance across its range. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C).

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across medical devices, electronics and electrical enclosures, and sanitary process lines.
