-128 RED SILICONE 70D O-RING

APG stocks the S70128, an AS568-128 red Silicone 70 Shore A O-Ring measuring an inside diameter of 1.487 in (37.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.693 in (43 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Silicone is specified for very good compression set resistance across its range and excellent electrical insulating properties. It resists weathering, dry heat, and extreme heat and cold. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Exposure to abrasive dynamic service or concentrated acids will shorten service life.

Common environments for this compound include food and beverage processing, electronics and electrical enclosures, and pharmaceutical manufacturing.

Stocked as S70128 and sold individually. Unit weight is approximately 0.949 g and nominal inside diameter is listed as 1 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
