Vibrant 18294 90 Degree Mandrel Bend 1.625" OD 4" CLR Aluminum

The Vibrant Performance 18294 is a precision-engineered 90-degree mandrel bent aluminum tube designed for custom exhaust and intake fabrication. This bend features a 1.625" outer diameter with a 4" centerline radius (CLR), providing smooth airflow with minimal turbulence and restriction.

Key Features:

• 90-degree bend angle for tight routing applications
• 1.625" (1-5/8") outer diameter tubing
• 4" centerline radius for optimal flow characteristics
• Mandrel bent construction maintains consistent inner diameter throughout the bend
• T6061 aluminum construction for excellent strength-to-weight ratio
• Prevents tube collapse and flow restriction common with crush bending
• Ideal for custom turbo piping, intercooler piping, intake tubes, and exhaust systems

Mandrel bending is the preferred method for performance applications because it maintains the tube's full inner diameter throughout the radius, eliminating the pinching and flow restrictions associated with traditional crush bending. This results in improved airflow efficiency and better overall performance.
