The S70MD327 is an AS568-327 red Silicone 70 Shore A O-Ring with an inside diameter of 1.725 in (43.82 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.145 in (54.48 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.
As a material, Silicone delivers excellent electrical insulating properties, physiological inertness and low toxicity. It resists many oxidizing chemicals, weathering, and ozone and UV exposure. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with concentrated acids or abrasive dynamic service.
The compound is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across ovens and heated equipment, electronics and electrical enclosures, and medical devices.
S70MD327 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. 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.
