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.
Product Notes
- Outside Diameter: 2.00" (50.8mm).
- Centerline Radius (CLR): 3.00" (76.2mm).
- Bend Angle: 90 degrees.
- Leg Length: 0" (no straight legs ends at bend radius).
- Commonly used for turbo manifold collectors, downpipe bends, and intercooler piping.
- Single bend – sold individually.
- Weight approximately 1.8-2.2 lbs.
Installation Notes
- Requires cutting and welding for custom fabrication.
- Professional exhaust builder recommended for pie-cut or TIG welding applications.
- Use 308L filler rod for best results when welding 304 stainless.

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.
