*METRIC NBR 70D 7MM X 174.6MM BLK

Item H7X174.6 is a Buna-N NBR 70A Metric O-Ring built for metric equipment, imported machinery, fluid power assemblies and replacement sealing applications. The item is specified by 174.6 mm (6.874 inch) ID x 7 mm (0.276 inch) CS; 188.6 mm (7.43 inch) OD, giving buyers a clear dimensional reference for matching the seal to the groove, shaft or bore. 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. Metric sizing supports imported equipment, metric gland designs and replacement work where inch-series AS568 dimensions do not apply. The each-unit format supports precise replacement, kitting, resale and job-specific purchasing. 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.
