Perfect for custom exhaust systems or intake manifold fabrication where tight bends are required.  May be cut to accommodate any degree of bend necessary , each Donut is capable of providing many pieces, and are often used in conjunction with regular U-bends . The inner seam requires finish welding after cutting.

   The other bonus to a Donut  over a conventional tight radius U-bend, is the wall thickness is consistent on the inside of radius and the outside radius . This is due to the method of manufacturing , and provides additional durability as the outside of the bend is not stretched paper thin .

   These tight radius Donuts are " 1-D " , which means the center line radius is equal to the outside diameter of the tube. 

   Example :  2 in.outside diameter tubing of a Donut is formed on a 2 in.center line radius. 

   Available in both mild steel or 304 stainless steel

One donut provides many bends - an excellent value!
