-394 RED SILICONE 70D O-RING

APG stocks the S70394, an AS568-394 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 24.94 in (633.48 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 25.36 in (644.14 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists extreme heat and cold, weathering, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is widely chosen for physiological inertness and low toxicity, very good compression set resistance across its range. Published continuous service range is -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with abrasive dynamic service or steam above its rated range.

It sees regular use in medical devices, food and beverage processing, and sanitary process lines.
