Bonded Seals
You need to be logged in to see prices.Bonded Seals consists of a metal outer ring and an inner ring of rubber elastomer that acts as a gasket to provide a sealing action. This design, often referred to as a Dowty Seal or Dowty Washer, is widely used as a bolt seal in hydraulic equipment but has found its way into many other industrial applications due to its reliable performance.
Bonded Seals available from stock with a Steel Washer zinc plated or 316 Stainless Steel washer with a trapezoidal shaped nitrile rubber ring bonded to its inner circumference.
They are used in circumstances where high pressures demand greater sealing capacity than can be obtained with copper washers. The metal ring prevents over compression and extrusion of the pliable ring.
Self-Centralising Bonded Seals can offer several advantages:
- Eliminates Seal Offset: Ensures the seal is perfectly positioned during installation.
- Prevents Leaks: Provides an extra safeguard against leakage even under demanding conditions.
- Ease of Installation: The self-centralising feature simplifies fitting, especially in awkward or restricted spaces.
- Reduces Assembly Time: Less fiddling means a quicker, more straightforward assembly process.
- Captive Assembly: Keeps the seal securely in place during installation, reducing the risk of misalignment.
These added features make Bonded Seals especially suitable for hydraulic, pneumatic, and other high-pressure applications where reliability is paramount.
The majority of our stocked Bonded Seals are self-centralising, please refer to the product description. White fluorosilicone also available, please contact us for further information.
