3MM CS X 18MM ID RED SILICONE 70D

APG stocks the S3X18, a red Silicone 70 Shore A O-Ring built to an inside diameter of 18 mm (0.709 in), a cross section of 3 mm (0.118 in), and an outside diameter of 24 mm (0.94 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against dry heat, weathering, and ozone and UV exposure. That behavior comes from the compound itself: Silicone is widely chosen for an exceptionally wide service temperature range and flexibility that holds at very low temperatures. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Applications involving concentrated acids or abrasive dynamic service call for a different compound.

This o-ring meets FDA requirements for food contact. Maintenance and OEM teams specify it across medical devices, pharmaceutical manufacturing, and electronics and electrical enclosures.

Reference part number S3X18 when ordering; the item is sold individually. Unit weight is approximately 0.653 g. Review your operating media and conditions against this specification before installation.
