-924 RED SILICONE 70D FDA O-RING

APG stocks the S70FDA924, an AS568-924 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 1.72 in (43.69 mm), a cross section of 0.118 in (3 mm), and an outside diameter of 1.956 in (49.68 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Silicone is specified here for very good compression set resistance across its range and exceptionally wide service temperature range. It resists ozone and UV exposure, dry heat, and weathering. 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 o-ring meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across sanitary process lines, medical devices, and pharmaceutical manufacturing.

Stocked as S70FDA924 and sold individually. Unit weight is approximately 1.5 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
