Rubber expansion joint series products: single sphere rubber expansion joint, double ball rubber expansion joint, concentric diameter rubber expansion joint, reducing rubber expansion joint, food grade rubber expansion joint, threaded connection rubber expansion joint.
1. Features of Reducer Flexible Rubber Expansion Joint:
1). Small volume, light weight, good elasticity, easy installation and maintenance.
2). Transverse, axial and angular displacements may occur during installation, which are not restricted by the pipeline not concentric and the flange not parallel.
3). When working, it can reduce the transmission noise and strong vibration absorption ability.
2. Suitable medium of Reduced Concentric Expans Compensator :
According to different material, acid resistance rubber joint, flameproof rubber joint, oil resistant rubber joint, thermostatic rubber joint, low temperature resistant rubber joint, wear resistance rubber joint can be made to suitable for various kinds of medium, and environment.
3. Applications of Rubber Expansion Joint:
Due to favourable integrated performance, they can be widely used in chemical industry, construction, water supply, drainage, oil industry, light and heavy industry, refrigeration station, water heating system, fire fighting system, electric power system, etc.

Q:Can the products be manufactuered by customer's requirement?
A:Yes, the specifications stated above are the standard ones, we can design and manufacture as requirement.
Q: Why does the ball get sucked flat when the rubber joint I bought before is working?
A: When the rubber joint is working, negative pressure appears inside the pipe, so the ball gets sucked flat; when there is negative pressure in the pipe, a negative pressure ring needs to be installed inside the rubber joint to ensure the normal operation of the rubber joint.
