-330 RED SILICONE 70D FDA O-RING

Ordered as S70FDA330, this is an AS568-330 red Silicone 70 Shore A O-Ring built to an inside diameter of 2.1 in (53.34 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.52 in (64.01 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against dry heat, weathering, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is widely chosen for very good compression set resistance across its range, physiological inertness and low toxicity. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Applications involving abrasive dynamic service or concentrated acids call for a different compound.

This item meets FDA requirements for food contact under 21 CFR 177.2600. Typical settings include food and beverage processing, electronics and electrical enclosures, and pharmaceutical manufacturing.

Order part number S70FDA330, sold individually. Unit weight is approximately 5.83 g and nominal inside diameter is listed as 2 1/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
