XRP Xtreme Racing Products 890003 #3 Copper Crush Washers, 10-Pack

XRP Xtreme Racing Products part number 890003 provides a convenient 10-pack of #3 copper crush washers designed for reliable sealing in automotive, motorsport, and performance applications. Each washer features a 3/8-inch inside diameter and is manufactured from copper with a natural finish for dependable compression and conformity against mating surfaces.
These crush washers are commonly used with AN fittings, fluid lines, plugs, and other threaded connections where a compressible metal seal is required. Copper construction allows the washer to deform under tightening pressure, helping accommodate minor surface irregularities and reduce the risk of leaks when properly installed. The #3 size makes this set a practical choice for maintaining compatible XRP systems and related racing hardware.
Whether used during initial assembly, routine service, or component replacement, XRP 890003 crush washers help support consistent sealing performance without adding unnecessary complexity to the installation. The 10-piece package provides useful spares for shop inventory, track-side repairs, or multiple service intervals. Always select the correct washer size and follow the fitting or manufacturer’s recommended torque specifications for the application.
