Looking for a reliable, fast and efficient sealing solution?

Discover the Bonded Seal – the smart combination of strength and security!

Bonded Seal, also known as Dowty seal, Bonded Washer or Multiseal, is a static sealing ring.  

The metal ring makes it resistant to high pressures and suitable for use in mechanical, pneumatic and hydraulic applications.

They are used for sealing flange connections, screw couplings, nuts and bolt heads.

Applications you can rely on:

• Hydraulic installations
• Pneumatic systems
• Oil and gas pipelines
• Machine construction and industry
• Offshore and energy projects

Whether it's oil, air, water or gas — with a Bonded Seal, you're always in good hands!

Efficiency and reliability in one ring!

• Reduces the need for additional sealing grooves
• Available in various material combinations for chemical resistance
• Ideally suited for oil, gas, water and air applications

The elastomer is firmly bonded (vulcanised) to the metal ring, creating a reliable and durable seal, even under high pressure.

For you, this means:

• No leaks — even under high pressure!
• Quick installation — no special tools required.
• Perfect seal — in one simple step.
• Suitable for all sectors — from hydraulics to automotive and offshore.

Self-centring bonded seals are also available!

The self-centring version has an extra centring rim that centres the seal and holds it in place to prevent leakage. This bonded seal is very easy to install.

• METAL RING: made from galvanised steel, aluminium or stainless steel.
• RUBBER PART: comes in NBR as standard.
• For use with chemicals or high temperatures, Viton, silicone or possibly EPDM are good alternatives.
• The bonded seal is available in inch, BSP, metric and inch sizes.
