*METAL DETECTABLE BUNA 70 568-227

This Buna-N NBR 70A Metal-Detectable O-Ring, item H70MD227, is designed for buyers who need a clear specification match for food processing, packaging, washdown and detectable sealing applications where material selection is critical. The item is specified by AS568-227; 2.109 inch (53.57 mm) ID x 0.139 inch (3.53 mm) CS; 2.387 inch (60.63 mm) OD, with 2 1/8 inch nominal ID; 1/8 inch nominal CS for cross-reference against common gland and replacement dimensions. Its Buna-N nitrile (NBR) material provides 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. Common purchasing identifiers for this product include the material name, O-ring type, dimensional size, hardness and intended sealing application. Those attributes make the item easier to compare for maintenance, OEM production, MRO replacement and reseller catalog use.
