What is a mandrel bend and why is it important for exhaust systems?

A mandrel bend is created using a flexible rod (mandrel) inside the tube during the bending process. This prevents the tube from collapsing or kinking on the inside of the bend, keeping the inner diameter consistent. For exhaust systems, this means smoother airflow and less restriction.

What does '1D radius' mean for this elbow?

The '1D radius' refers to the tightness of the bend. 'D' represents the outer diameter of the tube, so a 1D radius means the center of the bend is located one tube diameter away from the outer wall of the tube. In this case, with a 1.625-inch tube, the center of the bend is 1.625 inches from the edge.

What is SS304 stainless steel commonly used for?

SS304 stainless steel is a popular choice for exhaust components because it offers good resistance to corrosion and heat. It's durable and can withstand the harsh conditions found in exhaust systems, helping to extend the life of fabricated parts.

About this part

Product Details

This 90-degree elbow is made from SS304 stainless steel, a material known for its good corrosion resistance, making it a solid choice for exhaust fabrication. It features a 1.625-inch outer diameter and a tight 1D radius bend, meaning the center of the bend is only 1.625 inches from the tube's edge. This tight radius is useful when you need to make a sharp turn in a limited space, like routing exhaust under a vehicle.

The tubing wall is 16 gauge, which is .065 inches thick. This thickness offers a good balance between being strong enough to handle exhaust temperatures and vibrations without being overly heavy. Because it's a mandrel bend, the inside of the curve stays round and doesn't collapse, which helps maintain smooth exhaust flow and prevents restrictions. This particular elbow has no legs, meaning the ends are cut straight, ready for you to weld or connect to other tubing sections.
