Self Center Bonded Seal for Reliable Hydraulic and Fluid Connections

A self-centering bonded seal (also called a self-centering bonded washer or Dowty seal) is a static sealing component. It combines a rigid metal annular carrier with an elastomeric sealing element, bonded together to deliver reliable, low-leak performance under high pressure, temperature variation, and vibration.

Compared to traditional adhesive seals, self-centering lips or internal guides help keep the seal aligned with bolts or joints, thereby reducing installation errors and improving long-term seal reliability.

FAQ

01.What is a self center bonded seal?

A self-centering bonded seal is a metal gasket with an adhesive elastomeric sealing ring and a centering lip, designed to provide a reliable seal for threaded bolts and hydraulic fittings.

02.What is the advantage of the self-centering design?

The self-centering lip automatically aligns the seal with the bolt or joint, reducing installation errors and ensuring consistent sealing performance.

03.Can bonded seals handle high pressure?

Yes. The metal washer provides structural support that allows bonded seals to operate under high-pressure hydraulic conditions.
