Bonded seals are a type of gasket used to seal screws and bolts. It is called the Dowty Seal or Dowty Gasket because it was originally manufactured by the Dowty Group. It is now widely manufactured in a variety of materials and sizes.
Bonded seals consist of an elastic material used as a gasket and a hard material used as an outer ring. It is a sealing ring used to seal threaded and flanged connections.

Features: 1. Wear-resistant 2. Lubrication 3. Oil-resistant 4. High temperature resistance 5. Sealing, etc. Otherwise, it is easy to heat and wear when you go out dry.
1. The sealing lip of the rubber material is vulcanized on the metal edge for sealing the bolted connection or the installation room, suitable for all industrial purposes.
2. The existence of rubber material ensures the sealing performance of the internal interface, the connection is stable, and the fixing is safe.
3. The corresponding rubber material also provides the function of suitable combination gasket, so that it can work and seal normally.
4. The thickness of the imported custom-made core gasket metal ring limits the compression of rubber parts, eliminates the phenomenon of joint deformation beyond the limit, and ensures the reliability of the sealing system.
5. Internal pressure is applied to the sealing lip, which improves the sealing performance.

Bonded seal sealing principle:
It is the rubber on the inside of the steel ring that provides the sealing effect, usually NBR. Glued to the outer ring by heat and pressure. This structure has strong burst resistance and compression resistance. Some designs have an extra rubber flap on the inner diameter to position the bonded seal in the center of the hole, these are called self-centering bonded gaskets;
