-321 RED SILICONE 70D O-RING

Part number S70321 is an AS568-321 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 1.162 in (29.51 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.582 in (40.18 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

This material stands up to dry heat, ozone and UV exposure, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone offers very good compression set resistance across its range and flexibility that holds at very low temperatures. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service.

Common environments for this compound include electronics and electrical enclosures, food and beverage processing, and sanitary process lines.

S70321 ships individually. Unit weight is approximately 3.55 g and nominal inside diameter is listed as 1 3/16 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
