Bonded Seals

Description

The Bonded Seal (or Multiseal) is a static seal which is used as a sealing ring fitted under bolt heads and nuts. 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.
