-351 RED SILICONE 70D O-RING

Part number S70351 is an AS568-351 red Silicone 70 Shore A O-Ring built to an inside diameter of 4.725 in (120.02 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.145 in (130.68 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Silicone offers excellent electrical insulating properties and flexibility that holds at very low temperatures. The material holds up against extreme heat and cold, many oxidizing chemicals, and weathering. 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 concentrated acids or abrasive dynamic service are present.

Maintenance and OEM teams specify it across food and beverage processing, sanitary process lines, and electronics and electrical enclosures.

S70351 ships individually. Unit weight is approximately 12.33 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
