What is a mandrel bend and why is it important for exhaust tubing?

A mandrel bend uses a flexible internal support (the mandrel) to prevent the tubing from collapsing or kinking during the bending process. This ensures the inside diameter of the tube remains consistent, which is crucial for maintaining exhaust flow and preventing turbulence.

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

The '1.5D' refers to the bend radius relative to the tube's diameter. The '4.5in CLR' specifies the actual center line radius of the bend in inches. This combination describes the tightness and shape of the curve.

What is this tubing typically used for?

This type of tubing is commonly used by fabricators and DIYers to build custom exhaust systems, headers, or other custom piping applications where specific bends and diameters are needed.

About this part

Product Details

If you're fabricating a custom exhaust system, getting the bends just right is key to a clean install and good flow. This 3-inch diameter tubing from Stainless Bros is bent at a 45-degree angle using a mandrel process, which helps maintain the tube's shape and diameter through the bend.

This piece features a 1.5D bend radius, meaning the center line of the bend is 1.5 times the diameter of the tubing away from the center of the tube itself. It has one leg that's 5 inches long and another that's 8 inches long, giving you some flexibility when planning your exhaust layout. The stainless steel construction means it's well-built to resist corrosion, which is important for any exhaust component exposed to the elements.
