S70240 is an AS568-240 red Silicone 70 Shore A O-Ring built to an inside diameter of 3.734 in (94.84 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.012 in (101.9 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against many oxidizing chemicals, weathering, and dry heat. Silicone is specified for physiological inertness and low toxicity, flexibility that holds at very low temperatures. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C).

Maintenance and OEM teams specify it across electronics and electrical enclosures, medical devices, and pharmaceutical manufacturing.
