What is a UJ-bend and what is it used for?

A UJ-bend, also known as a U-joint bend or a tight radius bend, is a pre-formed section of tubing used in custom exhaust fabrication. It allows for sharp turns in tight spaces while maintaining good exhaust flow.

What does '1.5D radius' mean for this bend?

The '1.5D radius' refers to the bend's tightness. 'D' represents the tube's outer diameter (3 inches in this case). A 1.5D radius means the center of the bend is 1.5 times the tube diameter away from the tube's centerline, indicating a relatively smooth, less restrictive bend.

What is the wall thickness of this tubing?

This tubing has a 16-gauge wall thickness, which is approximately .065 inches. This is a common and durable thickness for custom exhaust applications, offering a good balance for welding and structural integrity.

About this part

Product Details

If you're building a custom exhaust system or fabricating a unique exhaust component, having the right tubing is key. This UJ-bend from Stainless Bros is made from SS304 stainless steel, which is known for its good corrosion resistance and durability. It's a 3-inch diameter tube with a 1.5D radius bend, meaning the center of the bend is 1.5 times the tube's diameter away from the tube's centerline. This provides a smooth, less restrictive flow path for your exhaust gases.

The tubing itself has a 16-gauge wall thickness, which is about .065 inches thick. This is a solid thickness for exhaust work, offering a good balance between strength and ease of welding. Each leg of the UJ-bend is 6 inches long, giving you enough material to work with when connecting it into your custom setup. This piece is ideal for fabricators looking for a well-built, pre-bent section of stainless steel tubing to simplify their build.
