APG stocks the S70MD168, an AS568-168 red Silicone 70 Shore A O-Ring supplied with an inside diameter of 7.237 in (183.82 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.443 in (189.05 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.
The material holds up against ozone and UV exposure, weathering, and dry heat. That behavior comes from the compound itself: Silicone is valued for physiological inertness and low toxicity, excellent electrical insulating properties. The material carries a published service range of -80°F (-62.2°C) to 450°F (232.2°C). Applications involving abrasive dynamic service or steam above its rated range call for a different compound.
The compound is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include electronics and electrical enclosures, food and beverage processing, and sanitary process lines.
Stocked as S70MD168 and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
