What does '1.5D' mean for this bend?

The '1.5D' refers to the bend radius. It means the center line of the bend has a radius that is 1.5 times the tube's outer diameter. For this 1.88-inch tube, the bend radius is approximately 2.82 inches.

Why is mandrel bending important for exhaust tubing?

Mandrel bending uses a solid core (the mandrel) inside the tube during the bending process. This prevents the tube from collapsing or kinking, ensuring the inner diameter stays consistent throughout the bend. This is important for maintaining proper exhaust flow.

What is 16-gauge steel typically used for in exhaust fabrication?

16-gauge steel is a common choice for custom exhaust systems. It offers a good balance of durability and workability, being strong enough for exhaust applications while still being relatively easy to cut, shape, and weld without excessive heat distortion.

About this part

Product Details

If you're fabricating a custom exhaust system, you'll need specific bends to route your tubing cleanly. This 45-degree mandrel bend from Stainless Bros is designed for that purpose. It's made from 16-gauge steel, which is a common thickness for exhaust work, offering a good balance between strength and ease of welding.

The 1.5D designation means the center line of the bend has a radius equal to 1.5 times the tube's diameter. For this 1.88-inch tube, that's a fairly tight radius, allowing you to make sharper turns in tighter spaces. Mandrel bending ensures the tube maintains its shape and diameter through the bend, preventing kinks or collapse, which is crucial for maintaining exhaust flow. This piece is ready for cutting and welding into your custom setup.
