5MM CS X 90MM ID RED SILICONE 70D

APG stocks the S5X90, a red Silicone 70 Shore A O-Ring with an inside diameter of 90 mm (3.543 in), a cross section of 5 mm (0.197 in), and an outside diameter of 100 mm (3.94 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

It resists many oxidizing chemicals, weathering, and extreme heat and cold. That behavior comes from the compound itself: Silicone is known for physiological inertness and low toxicity, very good compression set resistance across its range. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Exposure to concentrated acids or steam above its rated range will shorten service life.

This item meets FDA requirements for food contact. Maintenance and OEM teams specify it across medical devices, ovens and heated equipment, and sanitary process lines.

This item is sold individually under part number S5X90. Unit weight is approximately 8.0954 g. Review your operating media and conditions against this specification before installation.
