What is a mandrel bend?

A mandrel bend is created using a flexible internal support, called a mandrel, that prevents the tubing from collapsing or kinking during the bending process. This ensures the inside diameter remains consistent throughout the bend, which is important for exhaust flow.

What does '1.5D / 3.75in CLR' mean?

This refers to the bend radius. '1.5D' means the center of the tube bends around a radius that is 1.5 times its diameter. For a 2.50-inch tube, this results in a centerline radius (CLR) of 3.75 inches.

What is the benefit of stainless steel for exhaust tubing?

Stainless steel offers good resistance to rust and corrosion compared to standard steel. This makes it a popular choice for exhaust components that are exposed to moisture and road salt, helping the tubing last longer.

About this part

Product Details

This is a 2.50-inch diameter, 90-degree mandrel bend tube from Stainless Bros. It features a 1.5D bend radius, meaning the center of the tube bends around a radius that is 1.5 times its diameter, resulting in a 3.75-inch centerline radius. This piece has no legs, making it ideal for custom exhaust fabrication where precise cuts and welds are needed to connect sections.

Mandrel bending ensures the tube maintains its diameter and shape throughout the bend, which is crucial for maintaining exhaust flow and preventing restrictions. This is important for performance and sound. The stainless steel construction offers good resistance to corrosion, making it a solid choice for exhaust systems that need to hold up over time.
