Stainless Bros 304 Stainless Steel Mandrel Bend – 2.00″ OD / 1.5D Radius / 3.00″ Centerline Radius / 90 Degree / No Leg
The Stainless Bros 601-05056-3150 mandrel bend is a premium 304 stainless steel 90-degree tight-radius elbow designed for custom exhaust, intake, and intercooler fabrication. With a true 1.5D bend radius (3.00″ centerline) and no straight legs, this “pie cut” style bend provides the tightest possible radius in 2.00″ tubing for maximum flow and minimal turbulence – perfect for turbo manifold collectors, downpipes, charge piping, or any application requiring sharp turns without kinks or restrictions.
Key Features
- 304 Stainless Steel: T304 grade with bright annealed finish for corrosion resistance and weldability.
- True Mandrel Bent: No wrinkles or reduction in diameter full 2.00″ ID maintained throughout the bend.
- 1.5D Tight Radius: 3.00″ centerline radius (CLR) for compact routing.
- No Leg Design: Pure 90-degree bend with cut ends ideal for pie-cut welding or custom fitment.
- Wall Thickness: 16-gauge (0.065″) for strength and easy welding.
- Tangent Ends: Minimal straight section for precise custom fabrication.
- Made in Japan: Manufactured to Stainless Bros’ exacting standards.

Frequently Asked Questions
- Q: What is “no leg” mean?
A: The bend has zero straight tangent ends right at the radius for pie-cut welding or maximum tightness. - Q: Is this polished?
A: Bright annealed finish shiny but not mirror polished. - Q: Can I weld this to mild steel?
A: Possible but not recommended best results with 304 to 304 or 321 stainless.
