Vibrant aluminum transition is a polished 6063 adapter stepping from 3.5 in to 4 in tube sizes with a 3 in overall length. Designed for fabricators who prefer welded transitions over silicone couplers, it needs minimal TIG preparation and is bead-rolled for a consistent profile. The mirror-polished finish presents a professional appearance and a one-year limited warranty is included.
