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.

Fabrication

Fabrication parts and materials provide the raw components needed to build, repair, and modify custom exhaust systems, turbocharger plumbing, intercooler piping, fuel system lines, oil routing, and engine bay heat management on performance and competition vehicles. Stainless steel tubing, titanium tubing, aluminum charge piping, mandrel bends, pie cuts, flanges, merge collectors, V-band clamps, O2 sensor bungs, AN fittings, PTFE hose kits, braided fuel and oil lines, heat shields, and welding supplies are the backbone of any serious custom fabrication project. Professional fabricators, race team mechanics, and advanced DIY builders who want full control over exhaust routing, charge pipe layout, or fuel system plumbing choose raw fabrication materials rather than pre-bent kits because custom fabrication allows fitment solutions that no universal kit can accommodate. Brands including Vibrant Performance, Ticon Industries, Stainless Bros, Radium Engineering, Fragola, and DEI provide th...
