2.7 X 8.9 BUNA 70 METRIC ORING

Use item H2.7X8.9 when a Buna-N NBR 70A Metric O-Ring is required for metric equipment, imported machinery, fluid power assemblies and replacement sealing applications. The item is specified by 8.9 mm (0.35 inch) ID x 2.7 mm (0.106 inch) CS; 14.3 mm (0.56 inch) OD, giving buyers a clear dimensional reference for matching the seal to the groove, shaft or bore. The Buna-N nitrile (NBR) construction supports 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. Important product identifiers include O-rings, replacement seals, fluid sealing, material compatibility and dimensional fit. It supports customer comparison, distributor cataloging and specification-based selection without relying on pricing, availability or shipping claims.
