"Bonded Seals consist of an elastomer sealing lip vulcanized to the edge of a metal washer. They are used to seal
bolted connections and mounting elements in oil and gas applications such as pipe connections and couplings. When the bolted connection 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,
eliminating any over torque of the joint, thereby ensuring a reliable sealing system. The internal pressure increases the sealing force by energizing the sealing lip."
