Stainless Bros 601-10226-4150 4 Inch Diameter 45 Degree Mandrel Bend

The Stainless Bros 601-10226-4150 is a precision-engineered 4-inch diameter mandrel bend designed for custom exhaust fabrication. This 45-degree bend features a 1.5D (1.5 times diameter) bend radius with a 6-inch center line radius (CLR), providing smooth exhaust flow while maintaining consistent pipe diameter throughout the bend.

Key Features:

• 4-inch outer diameter for high-performance exhaust systems
• 45-degree bend angle with 6-inch leg length
• 1.5D bend radius (6-inch CLR) for optimal flow characteristics
• Mandrel-bent construction maintains consistent inner diameter
• Premium 304 stainless steel construction for durability and corrosion resistance
• 16-gauge (.065-inch) wall thickness for strength
• Precision-formed for clean, professional exhaust fabrication

This mandrel bend is ideal for custom exhaust builders and fabricators working on automotive, truck, or performance applications requiring smooth transitions and maximum exhaust flow. The mandrel bending process eliminates the crimping and flow restrictions common with crush-bent tubing, ensuring optimal exhaust velocity and power gains.
