Vibrant aluminum joiner coupling is a polished 6063 aluminum sleeve sized for a 1.5 in tube outside diameter with a 3 in length and 1.6mm wall thickness. Bead-rolled and mirror-polished, it needs little surface prep for TIG welding and is handy for custom silicone couplings, intercooler end tank work, or welding hose inlets to aluminum radiators. Includes a one-year limited warranty.
