*Metal Detectabl FDA Silicone 70 568-157

Use item S70MD157 when a Silicone 70A 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 AS568-157; 4.487 inch (113.97 mm) ID x 0.103 inch (2.62 mm) CS; 4.693 inch (119.2 mm) OD, with 4 1/2 inch nominal ID; 3/32 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. Its metal-detectable formulation supports detectable sealing applications where lost-part risk management is part of the specification. 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.
