-273 RED SILICONE 70D O-RING

Ordered as S70MD273, this is an AS568-273 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 9.734 in (247.24 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.012 in (254.3 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists dry heat, extreme heat and cold, and many oxidizing chemicals. That behavior comes from the compound itself: Silicone is widely chosen for very good compression set resistance across its range, physiological inertness and low toxicity. Rated temperature range runs from -80°F (-62.2°C) to 450°F (232.2°C) in continuous service. Applications involving hydrocarbon fuels and oils or abrasive dynamic service call for a different compound.

This item is metal detectable for HACCP and foreign-body control programs. It sees regular use in sanitary process lines, medical devices, and electronics and electrical enclosures.

Reference part number S70MD273 when ordering; the item is sold individually. Nominal inside diameter is listed as 9 3/4 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
