Item H70MD270 is a Buna-N NBR 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 AS568-270; 8.984 inch (228.19 mm) ID x 0.139 inch (3.53 mm) CS; 9.262 inch (235.25 mm) OD, with 9 inch nominal ID; 1/8 inch nominal CS for cross-reference against common gland and replacement dimensions. The Buna-N nitrile (NBR) compound is selected for oil, grease, fuel and general hydraulic fluid resistance in common industrial equipment. It is with a listed temperature range of -40°F (-40°C) to 250°F (121°C), which can help narrow material selection for heat, cold or process exposure. The black 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.
