-245 RED SILICONE 70D FDA O-RING

S70FDA245 is an AS568-245 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 4.359 in (110.72 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.637 in (117.78 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against many oxidizing chemicals, ozone and UV exposure, and extreme heat and cold. That behavior comes from the compound itself: Silicone is known for very good compression set resistance across its 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 abrasive dynamic service or concentrated acids call for a different compound.

The compound meets FDA requirements for food contact under 21 CFR 177.2600. You will find this material specified across ovens and heated equipment, electronics and electrical enclosures, and food and beverage processing.

S70FDA245 ships individually. Unit weight is approximately 4.891 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.
