-171 RED SILICONE 70D FDA O-RING

The S70FDA171 is an AS568-171 red Silicone 70 Shore A O-Ring built to an inside diameter of 7.987 in (202.87 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 8.193 in (208.1 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists extreme heat and cold, dry heat, and many oxidizing chemicals. Silicone is widely chosen for excellent electrical insulating properties and very good compression set resistance across its range. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Exposure to abrasive dynamic service 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 food and beverage processing, electronics and electrical enclosures, and medical devices.

S70FDA171 ships individually. Unit weight is approximately 5.04 g and nominal inside diameter is listed as 8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
