V-Band clamps have been around for ages. Some times called "Marmon clamps", they are used in a variety of commercial, industrial, and racing applications. In many cases the end of a tube/pipe is pressed to form the flange. We have designed a line weld on flanges that can be used to replace the old 3 bolt flange or slip and clamp connections. The precision CNC machined surface provides a gasketless seal. The T-bolt style latch allows the clamp to be installed quickly without removing the nut.
SPD V-Bands are designed for use with SPD Sealing Flanges. The advertised size refers to the outside diameter of the tubing that will slide through the inside diameter of the sealing flange.

Our V-Band clamps and sealing flanges are not designed specifically to be compatible with other manufactures flanges, such as turbine outlets.
See the diagram and chart (right) for compatibility.
