Bonded Seals

Bonded Seal represents a combination of metal washer and elastomer Sealing lip vulcanized to the inner face of the metal part to seal spiral leakage in bolted connection. Eg. Pipe connections and couplings.When the bolted connections is tightened,the sealing lip is pressed against the flat surfaces.The metal washer ensures that the components to be connected are reliably and securely held.The thickness of the washer limits the compression of the elastomer seal,eliminates any over torque of the joint,thereby ensuring a reliable sealing system.The internal pressure increases the sealing force by energying the sealing lip.

 

Self-Centralising to eliminate(the possibility of leakage due to)any offset which centers the seal at its location. All sizes are made as per International Standards.

 

Unique's manufacturing all type of Bonded Seals in all Inches Sizes(BSP) and Metric Sizes, Special sizes are made to Customer order.
