What is a V band flange?

What is a V band Flange? A universal V band flange is a method of connecting pipes together in conjunction with a v band clamp, The Vband flange is welded to the exhaust tube and then bolted together with the vband clamp. These are used mainly in the automotive industry for exhaust systems and waste gate return pipes.

Are all V band flanges the same?

There are two basic types of V-band flanges available, bulge-formed and machined. The bulge-formed flanges are formed from a tube that is “bulged” then collapsed to form a flat flange. Machined flanges are machined from metal stock. Machined flanges should be used with a gasket for most connections.

How are V band flanges measured?

Using a measuring tape or caliper, measure the outside diameter (OD) of the matching tube or pipe size that will be welded to the flange. If the tube or pipe is not available, measure the inside diameter (ID) of the counterbore of the weld side of the V-Band Flange.

Are V-band clamps worth it?

V-Bands have quite a few distinct advantages over flanges. V-Bands are much more compact than a Flange and this is the primary reason they were originally used on Turbochargers and in tight engine bays. They are much easier to access and work with. They never need glue or gaskets and can be reused over and over again.

How do you measure exhaust flange?

To measure such circle measure from the center of one bolt directly across to the center of the other bolt. The Outside Diameter is the measurement of the outside of the Flange or Gasket. The Inside Diameter is the measurement of the inside of the hole of a Flange or Gasket.

Are V-band clamps any good?

Another great advantage of a V-Band Clamp is the fact that the hotter they get the better they seal. Once the male and female ends are tight in position and the clamp is also firm and torqued up correctly, it is common knowledge that steel expands once its hot.
