-335 RED SILICONE 70D O-RING

Part number S70335 is an AS568-335 red Silicone 70 Shore A O-Ring with an inside diameter of 2.725 in (69.22 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.145 in (79.88 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to ozone and UV exposure, weathering, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is valued for an exceptionally wide service temperature range and very good compression set resistance across its range. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Applications involving abrasive dynamic service or concentrated acids call for a different compound.

Common environments for this compound include pharmaceutical manufacturing, electronics and electrical enclosures, and food and beverage processing.

Order part number S70335, sold individually. Unit weight is approximately 7.383 g and nominal inside diameter is listed as 2 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
