Vibrant 300 Series Stainless Steel V-Band Clamps are for use with their V-Band flanges which utilize a unique "Male/Female" flange design that ensures proper alignment inside the clamp. V-Band flanges are an excellent alternative to traditional flanged or slip fit tube connections. V-Band clamps offer a low profile and modular connection. They work especially well under operating conditions involving stress, vibration, and significant temperature fluctuations. The V-Band flanges are secured with a quick release clamp and allow for a gasket free seal as well as superior positive retention compared to other tube coupling methods. Vibrant V-Band flanges are counterbored for the tubing size you select, making welding simple.
