-042 RED SILICONE 70D O-RING

Part number S70MD042 is an AS568-042 red Silicone 70 Shore A O-Ring measuring an inside diameter of 3.239 in (82.27 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.379 in (85.83 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Silicone is specified here for flexibility that holds at very low temperatures, physiological inertness and low toxicity. This material stands up to dry heat, many oxidizing chemicals, and weathering. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Exposure to steam above its rated range or abrasive dynamic service will shorten service life.

The compound is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include ovens and heated equipment, sanitary process lines, and medical devices.

Order part number S70MD042, sold individually. Nominal inside diameter is listed as 3 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
