Straight Aluminum Tubing 5in O.D. x 18in Long

The Straight Aluminum Tubing 5in O.D. x 18in Long from Vibrant Performance is a precision component designed for custom intake manifolds, turbo piping, intercooler ducting, and exhaust fabrication in high-performance automotive builds. Whether you're constructing a cold air intake system, routing boost lines, or welding together a custom exhaust resonator, this aluminum tube provides the foundation for reliable, repeatable fabrication. Mechanics and fabricators rely on straight aluminum tubing for projects demanding both structural integrity and weight savings compared to steel alternatives.

Built from lightweight aluminum alloy, the 5-inch outer diameter tubing accommodates large-volume airflow and boost pressures without excessive wall thickness, making it ideal for turbo and supercharger applications. The straight 18-inch length provides ample stock material for cutting, notching, and bending to fit engine bay constraints or custom routing requirements. At just 3.03 lbs, this tubing minimizes unsprung weight while maintaining the wall thickness needed for pressure containment and weld penetration—critical factors when building systems that will endure heat cycles and vibration.

Fabricators working on LS-swaps, turbocharged four-cylinders, or small-block builds will find this tubing indispensable for custom mandrel bends and straight runs between components. Its 5-inch diameter works seamlessly with standard aluminum TIG and MIG welding techniques, and the material accepts bends and modifications without cracking or weakening. Whether you're building from scratch or repairing a damaged intake tract, this Vibrant Performance aluminum tube delivers the precision geometry and clean finish that separates professional fabrication from improvised solutions.
