Rubber Expansion Joints

Rubber expansion joints are used in the transportation of pressurized fluids. As they eliminate the need for coupling gaskets they are widely used in many industrial sectors. They are highly resistant to fatigue and corrosion and have a significant sound-proofing capacity

Different Types of Rubber Expansion Joints

Expansion Joint, Single Sphere

Expansion Joint, Twin Sphere

Expansion Joint, Union Type A

Expansion Joint, Union Type B
