Stainless Bros 4in Diameter 1D / 4in CLR 90 Degree Bend Leg Mandrel Bend

If you're fabricating a custom exhaust system, you'll need precise bends to route your tubing effectively. This 90-degree mandrel bend from Stainless Bros is designed for exactly that purpose. It's made from stainless steel, which is a solid choice for exhaust components because it holds up well against heat and corrosion.

The '1D' in the description refers to the bend radius, meaning the center line radius is equal to one times the tube's diameter. In this case, with a 4-inch diameter tube, the center line radius is 4 inches. This type of tight bend is useful when you need to make a sharp turn in a limited space. Mandrel bending ensures that the tube maintains its shape and diameter throughout the bend, preventing kinks or flattening that could restrict exhaust flow. This is crucial for getting the best performance out of your custom setup.

This piece is a great starting point for building custom exhaust sections, headers, or intake piping. It's a well-built component that gives fabricators the control they need to create a clean, efficient, and durable exhaust system.
