The Bonded Seal comprises a metal annulus, square or rectangular in section, to which an elastomeric ring of trapezoidal section is bonded. Developed to replace copper type washers in high-pressure hydraulic and pneumatic threaded connections, the metal ring resists the pressure bursting forces and limits the deformation of the elastomeric element. This prevents over-compression and extrusion.The standard type Bonded Seal is supplemented by a range of self-centering Bonded Seals that eliminate the possibility of leakage, by ensuring it is properly centered during assembly. Available in a wide range of aerospace and defense released materials. Custom designs are also available. Technical Drawing
