Vibrant 13133 15 Degree Mandrel Bend 3.5 Inch O.D. Aluminum Tubing

The Vibrant Performance 13133 is a precision-engineered 15-degree mandrel bent aluminum tube designed for custom exhaust systems, intake piping, and intercooler plumbing. This 3.50-inch outside diameter bend maintains consistent wall thickness and inner diameter throughout the curve, ensuring optimal flow characteristics without restrictions.

Key Features:

• 15-degree bend angle for gradual directional changes in custom piping applications
• 3.50-inch outside diameter (O.D.) aluminum construction
• Mandrel bent process prevents tube collapse and maintains uniform inner diameter
• Smooth interior surface minimizes turbulence and pressure drop
• Precision-formed for consistent fitment with other mandrel bent components
• Ideal for turbo systems, exhaust fabrication, and high-performance intake builds

Mandrel bending is the preferred method for performance applications because it uses an internal mandrel to support the tube walls during bending, preventing crimping and maintaining the full flow area. This 15-degree bend provides a gentle transition suitable for routing piping around obstacles while maximizing flow efficiency in custom fabrication projects.
