-335 RED SILICONE 70D FDA O-RING

Ordered as S70FDA335, this is an AS568-335 red Silicone 70 Shore A O-Ring measuring 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). The o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists ozone and UV exposure, extreme heat and cold, and dry heat. That behavior comes from the compound itself: Silicone is known for an exceptionally wide service temperature 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. Applications involving steam above its rated range or abrasive dynamic service call for a different compound.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. Common environments for this compound include pharmaceutical manufacturing, sanitary process lines, and food and beverage processing.

S70FDA335 ships individually. Unit weight is approximately 7.383 g and nominal inside diameter is listed as 2 3/4 inch. Check the compound against your process media, pressure and temperature before committing to a design.
