-032 RED SILICONE 70D FDA O-RING

Ordered as S70FDA032, this is an AS568-032 red Silicone 70 Shore A O-Ring measuring an inside diameter of 1.864 in (47.35 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.004 in (50.9 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Silicone is specified here for exceptionally wide service temperature range and very good compression set resistance across its range. The compound resists ozone and UV exposure, weathering, and extreme heat and cold. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Exposure to concentrated acids or hydrocarbon fuels and oils will shorten service life.

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

Reference part number S70FDA032 when ordering; the item is sold individually. Unit weight is approximately 0.562 g and nominal inside diameter is listed as 1 7/8 inch. Check the compound against your process media, pressure and temperature before committing to a design. 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.
