5.475" (139.07MM) ID X .210" (5.33MM)

Use item S70FDA357 when a Silicone 70A FDA Metal-Detectable O-Ring is required for food processing, packaging, washdown and detectable sealing applications where material selection is critical. The item is specified by AS568-357; 5.475 inch (139.07 mm) ID x 0.21 inch (5.33 mm) CS; 5.895 inch (149.73 mm) OD, with 5 1/2 inch nominal ID; 3/16 inch nominal CS for cross-reference against common gland and replacement dimensions. The Silicone construction supports 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. Important product identifiers include O-rings, replacement seals, fluid sealing, material compatibility and dimensional fit. It supports customer comparison, distributor cataloging and specification-based selection without relying on pricing, availability or shipping claims.
