568-221 SILICONE 70 FDA O-RING

Item S70FDA221 is a Silicone 70A FDA Metal-Detectable O-Ring built for food processing, packaging, washdown and detectable sealing applications where material selection is critical. The item is specified by AS568-221; 1.421 inch (36.09 mm) ID x 0.139 inch (3.53 mm) CS; 1.699 inch (43.15 mm) OD, with 1 7/16 inch nominal ID; 1/8 inch nominal CS for cross-reference against common gland and replacement dimensions. The Silicone compound is selected for flexibility across broad temperature swings and clean sealing applications that require a soft, compliant elastomer. It is with a listed temperature range of -80°F (-62.2°C) to 450°F (232°C), which can help narrow material selection for heat, cold or process exposure. The red color and round profile provide a practical visual identifier during receiving, stocking and installation. This category is commonly specified for processing environments, packaging equipment and washdown areas where seal identification matters. The each-unit format supports precise replacement, kitting, resale and job-specific purchasing. This product belongs to FDA and metal-detectable material options for food processing and detectable sealing applications. Key selection details include material, hardness, product type, cross-section, inside diameter, outside diameter and application. These specification details help customers and resellers compare the part by performance requirements rather than brand name alone.
