-261 RED SILICONE 70D O-RING

Part number S70261 is an AS568-261 red Silicone 70 Shore A O-Ring with an inside diameter of 6.734 in (171.04 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 7.012 in (178.1 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to extreme heat and cold, weathering, and ozone and UV exposure. That behavior comes from the compound itself: Silicone is widely chosen for very good compression set resistance across its range and flexibility that holds at very low temperatures. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). It is not the right choice where abrasive dynamic service or concentrated acids are present.

Maintenance and OEM teams specify it across medical devices, sanitary process lines, and food and beverage processing.

S70261 ships individually. Unit weight is approximately 7.396 g and nominal inside diameter is listed as 6 3/4 inch. 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.
