Flange and Gasketing Sealants

Flange and gasket sealing for the automotive industry.

H.B. Fuller’s flange and gasketing sealants allow for maximum clamp loading and positive sealing of mating flanges and housings. These liquid gasketing materials are ideally suited for applications where there are small gaps on rigid, metal-to-metal assemblies. They create a formed-in-place gasket, eliminating the need for large inventories of pre-cut gaskets. Our flange and gasketing sealants key into the surface of the flanges when they are mated together creating a positive, uniform seal in the joint. This material does not shrink, tear, or relax when fully cured, and it is not necessary to re-torque flange bolts when using these products. They are extremely durable materials that have exceptional pressure and chemical resistance. They are available in a full range of strengths, cure times, and viscosities to meet specific application requirements. H.B. Fuller’s flange and gasketing sealants are a total leak prevention system. They are single-component, solvent-free materials that fill voids, surface gaps, and irregularities, allowing for a positive seal between mating flanges along with improving the structural integrity of the assembly.
