What does '1.5D / 4.5in CLR' mean for this tubing?

The '1.5D' refers to the bend ratio, meaning the centerline radius of the bend is 1.5 times the tube's outer diameter. For this 3-inch tube, that results in a 4.5-inch centerline radius (CLR). This ratio helps maintain smooth airflow through the bend.

What is the benefit of mandrel bending?

Mandrel bending ensures the tube wall doesn't collapse or flatten during the bending process. This keeps the inside diameter consistent throughout the bend, which is important for optimal exhaust flow and preventing restrictions.

What material is this tubing made from?

This tubing is constructed from steel, offering a solid foundation for custom exhaust fabrication projects.

About this part

Product Details

This 3-inch diameter tubing from Stainless Bros features a 45-degree bend with a 1.5D (4.5-inch centerline radius) ratio. This specific bend ratio is important for exhaust fabrication because it helps maintain smooth airflow through the bend, reducing turbulence and backpressure compared to tighter bends. It's made from durable steel, ready for your custom exhaust projects.

The mandrel bending process ensures that the tube maintains its shape and diameter throughout the bend, preventing kinks or flat spots that can restrict exhaust flow. This is crucial for performance builds where every bit of airflow matters. Whether you're building a custom exhaust system from scratch or modifying an existing one, this piece offers a clean, consistent bend for a professional finish.
