What is a 1.5D bend ratio?

A 1.5D bend ratio means the centerline radius of the bend is 1.5 times the diameter of the tube. For this 3-inch tube, the centerline radius is 4.5 inches, which helps maintain exhaust flow by avoiding sharp angles.

Why is mandrel bending important for exhaust tubing?

Mandrel bending uses a solid core to support the tube during the bending process. This prevents the tube from collapsing or kinking, ensuring a consistent inner diameter and smoother exhaust flow compared to crush bending.

What kind of projects is this tubing typically used for?

This type of tubing is commonly used in custom exhaust fabrication. It's ideal for building or modifying exhaust systems, headers, or intake piping where specific bend angles and smooth transitions are required.

About this part

Product Details

Stainless Bros is known for providing a wide range of exhaust components and fabrication supplies. This particular piece is a 3-inch diameter mandrel bent tube, featuring a 15-degree bend with a 4.5-inch centerline radius. It's designed for custom exhaust fabrication projects where precise bends are needed.

The 1.5D bend ratio means the centerline radius is 1.5 times the tube's diameter, offering a smooth transition that helps maintain exhaust flow. Mandrel bending ensures the tube maintains its shape and diameter through the bend, preventing kinks or restrictions that can hurt performance. The 6.5-inch legs provide ample length for connecting to other exhaust sections.
