568-331 BUNA 70 DURO WHITE FDA

Item H70FDA331 is a Buna-N NBR 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 AS568-331; 2.225 inch (56.52 mm) ID x 0.21 inch (5.33 mm) CS; 2.645 inch (67.18 mm) OD, with 2 1/4 inch nominal ID; 3/16 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 white 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.
