FASTNER SEAL, ZINC PLATED STEEL

Item AFS600-0101-5/16 is a Buna-N NBR Fastener Seal built for sealing around bolts, screws, threaded connections and fastener heads where leakage control is required. The item is specified by 0.313 inch (7.94 mm) ID, 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 formed profile provide a practical visual identifier during receiving, stocking and installation. As a fastener or thread seal, it is suited for sealing around hardware where fluid migration through a joint must be controlled. The each-unit format supports precise replacement, kitting, resale and job-specific purchasing. 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.
