Stainless Bros 1.75in SS304 15 Deg Mandrel Bend - 1.5D Radius 16GA/.065in Wall 6.5in Leg / 6.5in Leg

The Stainless Bros STB601-04516-8150 mandrel bend is designed for custom automotive exhaust fabrication, tubing systems, and performance applications requiring a precise 15-degree change in direction. Constructed from SS304 stainless steel, this bend provides dependable corrosion resistance and durable performance in demanding under-vehicle and engine-bay environments.
Built with a 1.5D centerline radius, the bend supports smoother tubing transitions while helping maintain consistent flow through the system. The 1.75-inch tubing diameter, 16-gauge material, and 0.065-inch wall provide a practical balance of strength, weldability, and fabrication flexibility. Mandrel forming helps preserve the tubing’s internal profile through the curve, making this component well suited for TIG-welded exhaust and intake projects.
Each bend includes equal 6.5-inch legs for convenient positioning and trimming during fabrication. The straight sections provide room for accurate fitment, welding, and connection to additional tubing or exhaust components. Stainless Bros manufactures this part for builders, fabricators, and automotive enthusiasts who need a clean, repeatable bend for custom stainless steel systems.
