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

The '1.5D' refers to the bend ratio, meaning the center line radius is 1.5 times the tube's outer diameter. For this 3-inch tube, that results in a 4.5-inch center line radius (CLR).

Why is mandrel bending important for exhaust systems?

Mandrel bending ensures the tube's diameter stays consistent throughout the bend. This prevents kinking or collapsing, which can restrict exhaust gas flow and reduce performance.

What kind of projects is this tubing bend best suited for?

This bend is ideal for custom exhaust fabrication, including headers, downpipes, and cat-back systems where precise angles and smooth transitions are needed.

About this part

Product Details

If you're building a custom exhaust system, getting the bends just right is key to a clean install and good flow. This 90-degree mandrel bend from Stainless Bros is designed for fabricators who need precise angles and smooth transitions in their tubing.

This piece features a 3-inch outer diameter and a 1.5D bend ratio, meaning the center line radius is 4.5 inches. The mandrel bending process ensures the tube maintains its shape and diameter through the bend, preventing kinks or restrictions that can hurt exhaust flow. It's made from stainless steel, which holds up well against exhaust heat and corrosion. This particular bend doesn't have any legs, making it versatile for connecting different sections of tubing in your custom setup.
