.8 X 22.8 BUNA 70 METRIC ORING

This Buna-N NBR 70A Metric O-Ring, item H.8X22.8, is designed for buyers who need a clear specification match for metric equipment, imported machinery, fluid power assemblies and replacement sealing applications. The item is specified by 22.8 mm (0.898 inch) ID x 8 mm (0.315 inch) CS; 38.8 mm (1.53 inch) OD, giving buyers a clear dimensional reference for matching the seal to the groove, shaft or bore. 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. 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. 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.
