Vibrant HD Clamp Transition Ferrules w/ O-Ring for 4in O.D. to 3.50in HD

This is a Vibrant Performance HD Clamp Transition Weld Ferrule. It's made from 6061 aluminum and is designed to connect a 4-inch outside diameter tube to a 3.50-inch HD Clamp size assembly. This part is useful when you need to join tubing of different sizes in a custom exhaust or intake setup.

The ferrule includes an O-ring seal, which helps create a tight, leak-free connection when used with Vibrant's HD Clamp Assemblies. Using the right transition piece ensures a clean and professional-looking fabrication job, preventing leaks and maintaining the integrity of your system.
