Vibrant Performance U-J Mandrel Bent Tubing

3.5" O.D. Aluminized Mild Steel U-J Mandrel Bent Tubing for Custom Exhaust and Piping Applications

Part #: 12612

Overview

Vibrant Performance offers high-quality U-J Mandrel Bent Tubing designed for fabricators and automotive enthusiasts who require durable, precise, and versatile piping solutions. Whether you're building custom exhaust systems, headers, downpipes, intercooler piping, or other custom tubular assemblies, this 3.5-inch outer diameter tubing provides the flexibility and strength needed for professional-grade fabrication projects. Its unique design allows for multiple bends and substantial straight sections from a single piece, making it an ideal choice for complex piping configurations.

Constructed from aluminized mild steel, this tubing combines excellent corrosion resistance with affordability, ensuring your custom builds are both durable and cost-effective. The tubing's precise mandrel bends maintain consistent diameter and smooth airflow, which is essential for performance applications. With its innovative U-J bend design, you can achieve up to three separate bends and a significant straight segment, reducing the need for multiple fittings and simplifying your fabrication process.

Key Features

Vibrant's U-J Mandrel Bent Tubing is engineered for precision and versatility, making it suitable for a wide range of custom piping projects. The key features include:

• Unique U-J Bend Design: Combines an 18-degree bend with a 45-degree bend into a single, integrated piece, allowing for up to three distinct bends and a straight section from one tube.
• Material: Made from aluminized mild steel, offering excellent corrosion resistance and durability for long-lasting performance.
• Tube Diameter: 3.5 inches outer diameter, ideal for high-flow exhaust and intercooler piping applications.
• Tube Thickness: .065 inches (1.65mm), providing a balance of strength and flexibility for fabrication.
• Precision Mandrel Bends: Ensures smooth airflow and minimizes turbulence, which is critical for maintaining performance and efficiency.
• Versatile Use: Perfect for custom exhaust systems, headers, downpipes, intercooler piping, and other tubular assemblies requiring multiple bends and straight sections.
• Ease of Fabrication: Designed to facilitate fabrication, reducing the need for multiple fittings and simplifying installation.
• High-Quality Construction: TIG-welded and carefully manufactured to meet professional standards, ensuring consistent quality across each piece.

Construction & Design

This tubing features a robust aluminized mild steel construction, which provides excellent corrosion resistance while maintaining affordability. The mandrel bending process ensures that the tube's diameter remains consistent throughout the bends, preventing flow restrictions and turbulence. The innovative U-J bend design allows fabricators to achieve complex piping layouts with fewer components, saving time and reducing potential leak points. The combination of 18 and 45-degree bends in a single piece offers maximum flexibility for custom applications, enabling precise routing in tight spaces or complex configurations.

Installation & Fitment

This mandrel bent tubing is intended for professional fabrication and custom installation. It requires cutting, welding, and fitting to your specific application. The precise dimensions and bends make it easier for experienced fabricators to create complex piping layouts. No additional modifications or special tools are necessary beyond standard fabrication equipment. Proper welding and sealing are essential to ensure leak-free performance and longevity of your custom piping system.
