-356 RED SILICONE 70D O-RING

Ordered as S70MD356, this is an AS568-356 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 5.35 in (135.89 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.77 in (146.56 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists ozone and UV exposure, extreme heat and cold, and dry heat. That behavior comes from the compound itself: Silicone is widely chosen for physiological inertness and low toxicity, an exceptionally wide service temperature range. The material carries a published service range of -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.

This item is metal detectable for HACCP and foreign-body control programs. You will find this material specified across medical devices, pharmaceutical manufacturing, and sanitary process lines.

S70MD356 ships individually. Nominal inside diameter is listed as 5 3/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
