Abstract : A device for sealing the joint between ducts having sheet metal flanges mated with V-band coupings. Seal assemblies are interposed between the V-band coupling and the abutting duct flanges. As the V-band coupling is tightened to draw the ends of the duct flanges together the seal assembly is compressed, deforming the sealing material in contact with the duct flanges and effectuating a tight seal therebetween. A variety of seal assembly configurations are contemplated including those of continuous or segmented structure, those having compressible resilient materials or ductile metals as sealing materials, and those having a support band bonded to the sealing material for added structural rigidity.
