Stainless Steel Exhaust TubeStainless steel tubes combine excellent physical properties with remarkable resistance to the corrosive agents found in exhaust emissions. 304 stainless steel is the most cost effective grade of non-magnetic stainless steel for general applications.

For U-bends and J-bends
Determine the Center Line Radius (CLR) by measuring across the outside edges of the bend, subtracting the tubing O.D., and dividing by 2.

Leg lengths are approximate; usually within +/- .25″. 

Use 308 filler rod to weld 304 to 304
Use 309 filler rod to weld 304 to mild steel

Straight Length Tubing
Straight tubing is sold by the foot, based on the total length of the tubing.
It is cut to the length you specify.
Lengths up to 8 feet can be shipped UPS.
