Benefits of Rubber Expansion Joints
Expansion joints are primarily used to absorb all directional piping movements
Absorb movement and excellent against vibration and flutter in rigid piping systems
The internal density is high, and the elastic deformation is good.
Very little axial space and are lightweight good flexibility, easy installation, and maintenance
