-151 RED SILICONE 70D O-RING

Part number S70MD151 is an AS568-151 red Silicone 70 Shore A O-Ring with an inside diameter of 2.987 in (75.87 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.193 in (81.1 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to extreme heat and cold, ozone and UV exposure, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is known for physiological inertness and low toxicity, flexibility that holds at very low temperatures. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Applications involving abrasive dynamic service or steam above its rated range call for a different compound.

This o-ring is metal detectable for HACCP and foreign-body control programs. You will find this material specified across ovens and heated equipment, electronics and electrical enclosures, and sanitary process lines.

Reference part number S70MD151 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
