What are the standards for bonded sealing gaskets and how much does a self centering bonded seal cost？

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. The combination gasket is used for threaded pipe joints and screw plug sealing. It is generally used together with the ferrule type pipe joint to block the oil port. It is mainly used for the static sealing of the end face of the threaded connection of the hydraulic valve pipe joint.

Combination gaskets are available in metric and imperial sizes. Combination gaskets can be divided into A type and B type according to the structure; they can be divided into full package and half package according to the difference of rubber. The allowable working pressure is 400Kg/cm2 (39.2MPa), and the working temperature is between -25-80℃.

Hard material is usually steel, elastic material is usually nitrile rubber

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.

Advantage:

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.

Application: automotive, electronics, chemical, antistatic, flame retardant, food and other industries.
