BONDED SEALS
Bonded Seal (also known as Dowty Seal or Dowty Bonded Washer) represents a combination of metal washer and elastomer sealing lip vulcanised to the edge of the metal part to seal bolted connections and mounting elements in all industrial applications e.g. pipe connections and couplings. When the bolted connection is tightened, the sealing lip is pressed against the flat surfaces.
We produce all standard self-centering bonded seals, KDS bonded seals and can also supply Bonded Seal Kits in BSP and metric sizes or custom kits to suit customer requirements.
