What is a mandrel bend?

A mandrel bend is created using a flexible rod (mandrel) inside the tube during the bending process. This prevents the tube from collapsing or kinking, ensuring a smooth, consistent inner diameter through the bend, which is important for exhaust flow.

What does 1.5D / 2.4in CLR mean?

1.5D refers to the bend radius being 1.5 times the tube's outer diameter. For a 1.625-inch tube, this results in a centerline radius (CLR) of approximately 2.4 inches. This indicates a relatively tight bend compared to larger radius bends.

What is this tube typically used for?

This type of stainless steel mandrel bend is commonly used in custom exhaust fabrication, such as building headers, custom exhaust systems, or modifying existing ones where a smooth, consistent bend is needed.

About this part

Product Details

What you get here is a single 90-degree mandrel bend tube from Stainless Bros, made from stainless steel. It has a 1.625-inch outer diameter and features a 1.5D (1.5 times the diameter) radius bend, which results in a 2.4-inch centerline radius. Each leg measures 6.5 inches long, giving you plenty of material to work with for custom exhaust projects.

This type of bend is useful when you need to make a clean, smooth turn in your exhaust system without kinking the tubing. Mandrel bending ensures the tube's diameter stays consistent through the bend, which helps maintain good exhaust flow. The stainless steel construction means it's built to resist corrosion, a common issue with exhaust components exposed to the elements.
