What does '1.5D / 6in CLR' mean for this bend?

This refers to the bend radius. '1.5D' means the center of the bend is 1.5 times the tube's diameter away from the tube's edge. For a 4-inch tube, this results in a 6-inch 'Center Line Radius' (CLR).

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 a smooth, consistent inner diameter throughout the bend. This is crucial for maintaining optimal exhaust flow.

What are the benefits of using stainless steel for exhaust tubing?

Stainless steel is well-suited for exhaust systems because it offers good resistance to corrosion from moisture and road salt. It also handles the high temperatures generated by exhaust gases effectively, making it a durable material for custom fabrication.

About this part

Product Details

If you're fabricating a custom exhaust system, having the right bends on hand makes the job much smoother. This is a 4-inch diameter mandrel bend from Stainless Bros, featuring a 45-degree angle and a 1.5D radius, which means the center of the bend is 6 inches from the edge of the tube. Mandrel bending is key here because it ensures the tube maintains its shape and diameter through the bend, preventing kinks or flattening that can restrict exhaust flow.

This piece is made from stainless steel, which is a solid choice for exhaust work because it holds up well against heat and corrosion. The 45-degree angle gives you a good option for changing direction in your exhaust routing without needing multiple smaller bends. Having these pre-bent sections ready to go can save a lot of time and effort compared to trying to bend the tubing yourself, especially when you need consistent results.
