3MM CS X 40MM ID RED SILICONE 70D

APG stocks the S3X40, a red Silicone 70 Shore A O-Ring supplied with an inside diameter of 40 mm (1.575 in), a cross section of 3 mm (0.118 in), and an outside diameter of 46 mm (1.81 in). 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 offers excellent electrical insulating properties and an exceptionally wide service temperature range. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C).

The compound meets FDA requirements for food contact. Maintenance and OEM teams specify it across electronics and electrical enclosures, ovens and heated equipment, and pharmaceutical manufacturing.

Stocked as S3X40 and sold individually. Unit weight is approximately 1.33 g. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
