-174 RED SILICONE 70D FDA O-RING

Ordered as S70FDA174, this is an AS568-174 red Silicone 70 Shore A O-Ring with an inside diameter of 8.737 in (221.92 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 8.943 in (227.15 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists extreme heat and cold, many oxidizing chemicals, and dry heat. That behavior comes from the compound itself: Silicone offers an exceptionally wide service temperature range and excellent electrical insulating properties. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Exposure to hydrocarbon fuels and oils or steam above its rated range will shorten service life.

The compound meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across ovens and heated equipment, electronics and electrical enclosures, and pharmaceutical manufacturing.

This item is sold individually under part number S70FDA174. Unit weight is approximately 5.5 g and nominal inside diameter is listed as 8 3/4 inch. Review your operating media and conditions against this specification before installation.
