-174 RED SILICONE 70D O-RING

Part number S70174 is an AS568-174 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 8.737 in (221.92 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 8.943 in (227.15 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Silicone is specified here for very good compression set resistance across its range, physiological inertness and low toxicity. The compound resists extreme heat and cold, ozone and UV exposure, and weathering. Service temperature is rated from -80°F (-62.2°C) through 450°F (232.2°C). Applications involving concentrated acids or steam above its rated range call for a different compound.

It sees regular use in sanitary process lines, electronics and electrical enclosures, and ovens and heated equipment.
