Buna 70-3mmCSx25mmID-Black-Pk50

Use item SB-H3X25-50 when a Buna-N NBR 70A Bagged O-Ring Pack is required for organized replacement seal inventory, maintenance kits and repeat-use service parts. The item is specified by 25 mm (0.984 inch) ID x 3 mm (0.118 inch) CS; 31 mm (1.22 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. 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. 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.
