Stainless Bros 601-10256-3100 4" Stainless Steel 90° Mandrel Bend Elbow 1D Tight Radius 16GA

The Stainless Bros 601-10256-3100 is a premium 4-inch diameter 90-degree mandrel bent elbow designed for high-performance exhaust and tubing systems. This tight radius bend features a 1D (one times diameter) centerline radius, providing the most compact turning solution for space-constrained applications.

Key Specifications:

• Material: SS304 stainless steel for excellent corrosion resistance and durability
• Diameter: 4 inches
• Bend Angle: 90 degrees
• Centerline Radius: 1D (tight radius - approximately 4 inches)
• Wall Thickness: 16GA (.065 inches)
• Construction: Mandrel bent for smooth, unrestricted flow
• Configuration: No leg design (elbow only, no straight extensions)

Features & Benefits:

• Mandrel bending process maintains consistent inner diameter throughout the bend, eliminating flow restrictions
• Tight 1D radius ideal for tight engine bay installations and space-limited routing
• 304 stainless steel construction provides superior heat resistance and longevity
• 16-gauge wall thickness offers an excellent balance of strength and weight
• No-leg design allows for maximum fabrication flexibility and precise custom fitment

Perfect for custom exhaust fabrication, turbo systems, intercooler piping, and marine exhaust applications where tight bends and reliable performance are essential. The no-leg configuration makes this elbow ideal for welding directly to straight tubing at exact lengths determined by your specific application.
