Vibrant Performance v - band flanges are constructed entirely from a 300 series stainless steel clamp that features a unique quick release clamping mechanism, and a unique malefemale CP1 grade titanium flange design to ensure proper alignment inside the clamp. Vibrant Performance v - band flanges are an excellent alternative to traditional flanged or slip tube connections and work well under operating conditions involving stress, vibration and significant temperature fluctuations. They are available in diameters that support O.D. tubing ranging from 2.5 to 4.
