Buna 70-2.5mmCSx12mmID-Black-Pk100

Item SB-H2.5X12-100 is a Buna-N NBR 70A Bagged O-Ring Pack built for organized replacement seal inventory, maintenance kits and repeat-use service parts. The item is specified by 12 mm (0.472 inch) ID x 2.5 mm (0.098 inch) CS; 17 mm (0.67 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. The bagged pack structure is well suited for distributors, maintenance departments and users who repeatedly service the same seal size. The bagged unit format is useful for organized maintenance inventory, reseller stocking and repeat replacement work. 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.
