-250 RED SILICONE 70D O-RING

Ordered as S70250, this is an AS568-250 red Silicone 70 Shore A O-Ring built to an inside diameter of 4.984 in (126.59 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.262 in (133.65 mm). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

This material stands up to many oxidizing chemicals, extreme heat and cold, and ozone and UV exposure. That behavior comes from the compound itself: Silicone is widely chosen for flexibility that holds at very low temperatures and excellent electrical insulating properties. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. It is not the right choice where steam above its rated range or hydrocarbon fuels and oils are present.

You will find this material specified across sanitary process lines, medical devices, and food and beverage processing.

Reference part number S70250 when ordering; the item is sold individually. Unit weight is approximately 5.63 g. Check the compound against your process media, pressure and temperature before committing to a design.
