What is a mandrel bend?

A mandrel bend is created using a flexible internal support (a mandrel) that prevents the tubing from collapsing or kinking during the bending process. This ensures the tube's diameter stays consistent throughout the bend, which is crucial for maintaining exhaust flow.

What does 1.5D / 3.75in CLR mean?

This refers to the bend radius. '1.5D' means the center of the bend is 1.5 times the tube's outer diameter away from the tube's centerline. For a 2.50-inch tube, this results in a 3.75-inch centerline radius (CLR).

What is this tubing typically used for?

This type of stainless steel tubing is commonly used for custom exhaust system fabrication, including headers, downpipes, and cat-back systems. Its specific bend allows for tight routing around chassis components.

About this part

Product Details

If you're building a custom exhaust system, you know how important it is to have the right bends to route your piping cleanly. This 180-degree mandrel bend from Stainless Bros is designed to help you achieve that. It's made from stainless steel, so you don't have to worry about rust or corrosion, even in harsh conditions.

This piece of tubing features a 2.50-inch outer diameter and a 1.5D bend radius, which means the center of the bend is 3.75 inches from the tube's edge. The 6-inch legs on either side give you plenty of room to work with when connecting it to other sections of your exhaust. Mandrel bending ensures that the tube maintains its shape and diameter through the bend, preventing kinks and maintaining good exhaust flow.
