1MM CS X 28MM ID RED SILICONE 70D

The S1X28 is a red Silicone 70 Shore A O-Ring supplied with an inside diameter of 28 mm (1.102 in), a cross section of 1 mm (0.039 in), and an outside diameter of 30 mm (1.18 in). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to ozone and UV exposure, weathering, and dry heat. That behavior comes from the compound itself: Silicone is widely chosen for an exceptionally wide service temperature range, physiological inertness and low toxicity. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Verify compatibility before use with abrasive dynamic service or steam above its rated range.

The compound meets FDA requirements for food contact. Maintenance and OEM teams specify it across electronics and electrical enclosures, food and beverage processing, and medical devices.

Stocked as S1X28 and sold individually. Unit weight is approximately 0.088 g. Check the compound against your process media, pressure and temperature before committing to a design. 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.
