Ordered as S70MD154, this is an AS568-154 red Silicone 70 Shore A O-Ring measuring an inside diameter of 3.737 in (94.92 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.943 in (100.15 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
Silicone is specified here for exceptionally wide service temperature range, physiological inertness and low toxicity. The material holds up against many oxidizing chemicals, weathering, and dry heat. Continuous operating temperature is published at -80°F (-62.2°C) to 450°F (232.2°C). Verify compatibility before use with steam above its rated range or abrasive dynamic service.
This o-ring is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include electronics and electrical enclosures, pharmaceutical manufacturing, and sanitary process lines.
Reference part number S70MD154 when ordering; the item is sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
