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.
One distinct advantage of a Donut over a conventional tight radius U-bend, is the wall thickness is more consistent . This provides additional durability over mandrel bent counterparts when needed, as the outside of the bend is not stretched paper thin. This is a result of the special method of manufacturing of a Donut
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!
