3MM CS X 75MM ID RED SILICONE 70D

S3X75 is a red Silicone 70 Shore A O-Ring with an inside diameter of 75 mm (2.953 in), a cross section of 3 mm (0.118 in), and an outside diameter of 81 mm (3.19 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to weathering, extreme heat and cold, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is widely chosen 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). Exposure to abrasive dynamic service or concentrated acids will shorten service life.

This item meets FDA requirements for food contact. You will find this material specified across sanitary process lines, ovens and heated equipment, and pharmaceutical manufacturing.

S3X75 ships individually. Unit weight is approximately 2.3928 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. 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.
