What is a mandrel bend?

A mandrel bend is created using a flexible internal support (a mandrel) that prevents the tubing from collapsing or kinking during the bending process. This ensures the inside diameter of the tube remains consistent throughout the bend, which is important for optimal exhaust flow.

What does 1.5D bend radius mean?

The '1.5D' refers to the bend radius relative to the tube's diameter. In this case, the centerline radius of the bend is 1.5 times the outer diameter of the tube (1.5 x 1.88 inches = 2.82 inches), which is the specified centerline CLR.

What is this tubing typically used for?

This type of tubing is commonly used by fabricators for custom exhaust systems, intake piping, or other applications where precise, smooth bends are required to route tubing around obstacles in a vehicle's chassis.

About this part

Product Details

This listing is for a single piece of Stainless Bros 45-degree mandrel bend tubing. You get one 1.88-inch outer diameter (OD) tube, bent at a 45-degree angle with a 1.5D bend radius, resulting in a 2.82-inch centerline (CLR) radius. The legs measure 5 inches and 8 inches respectively. This type of tubing is commonly used in custom exhaust system fabrication where precise bends are needed to route pipes around chassis components.

The mandrel bending process ensures that the tube maintains its full diameter throughout the bend, preventing kinks or flat spots that can restrict exhaust flow. This is crucial for performance applications where maintaining smooth airflow is important. The stainless steel construction offers good resistance to corrosion, making it a solid choice for exhaust components that are exposed to the elements.
