-156 RED SILICONE 70D O-RING

Item S70MD156 is a Silicone 70A Metal-Detectable O-Ring built for food processing, packaging, washdown and detectable sealing applications where material selection is critical. The item is specified by AS568-156; 4.237 inch (107.62 mm) ID x 0.103 inch (2.62 mm) CS; 4.443 inch (112.85 mm) OD, with 4 1/4 inch nominal ID; 3/32 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. Its metal-detectable formulation supports detectable sealing applications where lost-part risk management is part of the specification. 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.
