What is a '1D' radius bend?

A '1D' radius bend means the center of the tube follows a curve where the radius of that curve is equal to the tube's outer diameter. For this 1.88-inch tube, the bend's center line has a 1.88-inch radius.

What does 'no leg' mean for this tube?

A 'no leg' bend means the tube is cut right at the start and end of the bend itself. There are no straight sections, or 'legs,' extending from the curved portion.

What is the advantage of mandrel bending for exhaust systems?

Mandrel bending uses a mandrel inside the tube during the bending process. This prevents the tube from collapsing or kinking, maintaining a consistent internal diameter and allowing for better exhaust gas flow compared to crush bends.

About this part

Product Details

This listing is for a single Stainless Bros 1.88 inch diameter, 16-gauge steel tube with a 90-degree mandrel bend. The bend has a 1-diameter radius, meaning the center of the tube follows a curve with a radius equal to its diameter. This piece does not include a leg, meaning it's a clean bend without any straight sections extending from the ends.

Mandrel bending is important for exhaust fabrication because it maintains the tube's internal diameter throughout the bend, preventing kinks or flat spots that can restrict exhaust flow. This 16-gauge steel construction offers a good balance of strength and weldability for custom exhaust projects. It's a common component for building custom exhaust systems, headers, or intake piping where precise bends are needed.
