Similar to a standard washer, a 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. The flexing action of the lips under pressure provides a positive and leakproof seal against a wide range of fluids. The face to face sealing performance eliminates groove cutting or special machining and reduced bolting torque.
