The V-Band Flanges are machined for the appropriate size tubing OD (Outer Diameter).

For example, if your tubing is a 3" tubing, then select the 3" V-Band Flange

All Flanges are CNC Machined from a solid billet piece to provide reliable connection without the need of gasket.  Unlike the heat rolled or metal rolled flanges that warped easily due to its thin material, our flanges do not warp under normal usage and easy to weld.

Price is for ONE (1) Flange.  A complete pipe to pipe connection requires two flanges, while a downpipe setup only require one flange.
