1.5MM CS X 3.5MM ID RED SILICONE 70D

Ordered as S1.5X3.5, this is a red Silicone 70 Shore A O-Ring with an inside diameter of 3.5 mm (0.138 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 6.5 mm (0.26 in). The o-ring compresses into its gland to block fluid or gas migration across a joint. This item is further identified as Metric O-RING, JIS S4.

The material holds up against ozone and UV exposure, extreme heat and cold, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is valued for flexibility that holds at very low temperatures and excellent electrical insulating properties. Published continuous service range is -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.

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

This item is sold individually under part number S1.5X3.5. Unit weight is approximately 0.038 g. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
