NUCO manufactures hydroformed Sheet Metal Flanges to provide lightweight pneumatic duct joints where a minimal leakage rate is permissible. Sheet metal flanges seal on their faces and do not use a separate seal or gasket.

Sheet Metal Flanges are available in the standard large or wide radius and the narrow, low or tight radius profiles. Flanges are available for tube sizes from 1.00 to 10.00 inches and from a variety of materials such as corrosion resistant steel (CRES) 321, nickel alloys 625 and 718, commercially pure titanium A40, A55 and A70 and alloyed Ti-15-3-3-3.
