FASTNER SEAL, STEEL PLATED,

Use item AFS600-0101-1 when a Buna-N NBR Fastener Seal is required for sealing around bolts, screws, threaded connections and fastener heads where leakage control is required. The item is specified by 1 inch (25.4 mm) ID, 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 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. 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.
