-318 RED SILICONE 70D O-RING

APG stocks the S70MD318, an AS568-318 red Silicone 70 Shore A O-Ring measuring an inside diameter of 0.975 in (24.77 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.395 in (35.43 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, physiological inertness and low toxicity. The compound resists many oxidizing chemicals, dry heat, and weathering. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Applications involving concentrated acids or hydrocarbon fuels and oils call for a different compound.

This item is metal detectable for HACCP and foreign-body control programs. Typical settings include medical devices, pharmaceutical manufacturing, and food and beverage processing.

Order part number S70MD318, sold individually. Nominal inside diameter is listed as 1 inch. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
