Vibrant Aluminum Joiner Coupling (3.5in Tube O.D. x 3in Overall Length)

Vibrant Performance is a well-known name in the fabrication world, often relied upon for their exhaust and intake components. This aluminum joiner coupling is a perfect example of the kind of part that makes their reputation strong. It's designed to help you create custom silicone coupling setups, making it incredibly useful for fabricating intercooler end tanks or adding hose inlets and outlets to aluminum radiators.

This particular joiner is made from 6063 aluminum, which is a solid choice for fabrication projects because it requires minimal surface prep before TIG welding. That means less time spent cleaning and more time getting your project welded up. It has a 3.5-inch outer diameter for the tube and is 3 inches long, with a mirror-polished finish that looks great on custom builds. The bead-rolled design adds a bit of extra grip for silicone hoses, too.
