Stainless Bros 4in SS321 45 Deg Mandrel Bend Elbow - 1D Radius 16GA/.065in Wall (No Leg)

If you're fabricating a custom exhaust system, having the right bends is crucial for a smooth flow and proper fit. This 4-inch, 45-degree mandrel bend elbow from Stainless Bros is made from SS321 stainless steel, a material known for its excellent resistance to high temperatures and corrosion, making it a solid choice for exhaust applications.

The 1D radius means the bend is tight, with a centerline diameter equal to the tubing's diameter, which helps keep the exhaust gases flowing efficiently without excessive restriction. The 16-gauge (0.065-inch) wall thickness offers good durability for exhaust work. Since it's a mandrel bend, the tubing maintains its round shape and consistent diameter throughout the bend, which is important for performance and sound. This elbow is designed without legs, meaning it's a clean 45-degree cut on both ends, ready for you to weld into your custom piping.
