Bonded Seals are also known as Dowty Seals or Dowty Bonded Washers.They are high pressure seals which are used in the Mechanical, Hydraulic and Pneumatic sectors.They comprise of a metal washer and an elastomeric ring which is bonded inside the diameter.The metal washer prevents over-compression and limits deformation of the elastomeric ring.

BS/A self-centering combination sealing gaskets are suitable for metric, imperial, BSP threaded pipe joints and screw plugs. No special processing of the sealing groove position is required. It is an ideal accessory for fast and automatic installation. The operating temperature is -30℃~100℃, and the working pressure shall not exceed 39.2MPa. Non-automatic centering combination gaskets are suitable for pipeline systems with oil as the medium, for welding, ferrules, expansion pipe joints, screw plugs and pressure system sealing of mechanical devices. To prevent leakage of oil, fuel, water and medicines, the nominal pressure is up to 40MPa and the working temperature is -25℃~+100℃.
