METRIC 70 DURO BUNA ORING KIT - WHITE BX

This Buna-N NBR 70A O-Ring Kit, item M70K, is designed for buyers who need a clear specification match for maintenance, repair, field service and inventory coverage across multiple O-ring sizes. This item should be matched using its material, hardness, product category and item number when dimensional attributes are not provided in the row. 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. As an O-ring kit, it supports maintenance coverage, field repair readiness and organized replacement seal selection. 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.
