-133 RED SILICONE 70D O-RING

The S70MD133 is an AS568-133 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 1.799 in (45.69 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.005 in (50.93 mm). This 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 weathering. That behavior comes from the compound itself: Silicone is valued for flexibility that holds at very low temperatures, physiological inertness and low toxicity. 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 hydrocarbon fuels and oils.

This o-ring is metal detectable for HACCP and foreign-body control programs. It sees regular use in ovens and heated equipment, food and beverage processing, and medical devices.
