Stainless Bros 1.625in SS321 90 Deg Mandrel Bend Elbow - 1.5D Radius 16GA/.065in Wall (Leg)

When you're fabricating a custom exhaust system, having the right bends is crucial for a clean and efficient layout. This 90-degree mandrel elbow from Stainless Bros is designed for just that purpose. It's made from SS321 stainless steel, a material known for its good corrosion resistance and ability to handle high temperatures, making it a solid choice for exhaust components.

The 1.625-inch outer diameter and 1.65-inch inner diameter mean it's sized for common exhaust tubing. The 1.5D radius provides a smooth, gradual bend, which helps maintain exhaust flow without creating excessive backpressure. This is important for engine performance. The 16-gauge (0.065-inch) wall thickness offers a good balance between strength and weldability, suitable for most fabrication projects. Using mandrel bends like this ensures the tubing maintains its shape and diameter through the curve, unlike crush bends which can restrict flow.
