The Stainless Bros 601-03526-4100 is a 1.375-inch 304 Stainless Steel 45-Degree Mandrel Bend Elbow featuring a 1D centerline radius (CLR) and a leg extension for easy coupling to straight tubing sections. Designed for high-performance exhaust, intake, and intercooler piping fabrication, this elbow delivers precise bends without wall thinning or distortion.

Key Features:

• Material: 304 Stainless Steel — excellent corrosion resistance and high-temperature durability
• Diameter: 1.375 inches (1-3/8")
• Bend Angle: 45 degrees
• Radius: 1D / 1.375" centerline radius for smooth airflow
• Wall Thickness: 16GA / .065" — consistent wall thickness throughout the bend
• Style: With Leg — allows for direct connection to straight tubing
• Construction: Individually mandrel-extruded; ends are laser cut for precise fitment
• Finish: Ultrasonically cleaned for a show-quality surface ready to weld, polish, or leave raw

Stainless Bros elbow tubing is precision-manufactured to maintain a consistent 16GA/.065" wall thickness throughout the entire bend — a quality advantage over lesser alternatives. The laser-cut ends ensure accurate mating with straight tubing and other fittings, making this elbow ideal for custom exhaust fabrication, turbo piping, and performance intake systems.
