1-1/2" THREAD SEAL STEEL PLATED

Use item ATS7500-1-1/2 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 1.5 inch (38.1 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.
