Fastener seals consist of an inner rubber component used with an outer metal washer that supports the sealing function of a fastener such as a screw or a bolt. The combination eliminates any clearance gaps between the housing components and protects against potential leaks. Dichtomatik fastener seals cover a variety of applications including bolts, screws and tube fittings to provide a reliable sealing function. Functional Principle Thread, fastener and bonded seals are used to seal off potential leak paths on threaded fasteners such as bolts or threaded rods. Fasteners compress a predetermined amount once installed reducing the gap between the fastener and the mating components. Product Characteristics Standard rubber material is NBR Standard metal is zinc-plated carbon steel US Bonded Seals and USZO Fastener Seals Similar to a standard washer, a US bonded seal combines the rigidity of an outer metal ring along with a flexibility of an inside rubber seal. The metal washer provides much needed support while keeping the inner rubber seal from being over compressed and eliminating gaps to create a form-fitting seal. USZL Thread Seals USZL thread seals differ slightly from other fastener seals in appearance and application. The inner rubber seal has a triangular shape design for sealing directly against the threads of the fastener. USZL thread seals will prevent fluid from leaking out past the bolt through the threaded seal and can easily be assembled and disassembled as needed from contact surfaces without the use of special tools. USZL thread seals are readily available in standard fastener sizes and can be reused with proper removal.
