Ordered as S70426, this is an AS568-426 red Silicone 70 Shore A O-Ring built to an inside diameter of 4.6 in (116.84 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.15 in (130.81 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Expect good resistance to many oxidizing chemicals, dry heat, and weathering. That behavior comes from the compound itself: Silicone is known for physiological inertness and low toxicity, an exceptionally wide service temperature range. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C).
It sees regular use in electronics and electrical enclosures, sanitary process lines, and medical devices.
S70426 ships individually. Unit weight is approximately 21.64 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
