CVS® 6U, 6TU, 6HU, 6IU clamps: 40˚ V-Band clamps

The CVS® 6 clamp consists of an integral 40°-profile band, a screw, a washer and a nut.

It ensures tight connections on applications that can be forged, machined or formed on pipes.

CVS® 6 clamps are produced in different materials, depending mainly on application temperature:

  • Ferritic CVS® 6U (1.4509 stainless steel).
  • Austenitic CVS® 6TU (1.4541 stainless steel).
  • High performance austenitic CVS® 6HU (1.4571 stainless steel).
  • Inconel CVS® 6IU.


  • Robustness & reliability: one piece design without any welding.
  • Generates high clamping force and withstands high stresses (pressure, pull-off, vibration).
  • Cost optimized solution for 40° interfaces.
  • Allowable leak rate lower than 0.1 litre/min at 0.3 bar depending on interface quality and gasket type (graphite, mica, stainless steel, inconel…).
  • Withstands corrosion (resistance to salt spray over 400 hours).
  • Assembly and removal with manual tool or power screwdriver.
  • Any width & profile available on demand.
  • Bolts and nuts are available in coated carbon steel or stainless steel versions.
