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

A mandrel bend is created using a flexible mandrel inside the tubing during the bending process. This prevents the tube from collapsing or kinking, ensuring a consistent inner diameter throughout the bend. For exhaust systems, this smooth, consistent flow helps reduce backpressure and maintain optimal performance.

What does '1.5D' or '2.25in CLR' mean for this tube?

These terms refer to the bend radius. '1.5D' means the center line radius (CLR) of the bend is 1.5 times the tube's outer diameter. For a 1.50-inch tube, this results in a CLR of 2.25 inches. A tighter radius like this is useful for fitting exhaust components into tight spaces.

What kind of steel is this tube made from?

The product description indicates the tube is made from steel. While specific alloy details are not provided, steel is a common and durable material for exhaust fabrication.

About this part

Product Details

This 90-degree mandrel bend tube from Stainless Bros features a 1.50-inch outer diameter and a tight 1.5D (or 2.25-inch center line radius) bend. Mandrel bending means the tube's diameter stays consistent through the bend, which is crucial for maintaining smooth exhaust flow and preventing turbulence. This is important for custom exhaust systems where precise routing and optimal performance are key.

Constructed from durable steel, this 6.5-inch leg by 6.5-inch leg tube is ready for fabrication. Whether you're building a custom exhaust for a project car, repairing a damaged section, or modifying an existing system, the consistent bend radius ensures a predictable fit and smooth transition. The 1.50-inch diameter is a common size for many performance and custom exhaust applications.
