Double ball rubber expansion joint Introduce

Rubber expansion joint is a common pipe connector, also known as rubber soft connection, which is mainly composed of rubber and steel wire. The main role is to connect the pipeline, play the role of connection, shock absorption, noise reduction and so on. It can withstand a certain pressure and displacement in the pipeline connection, so as to ensure the normal operation of the pipeline. Compared with traditional metal pipe fittings, it has better elasticity and flexibility, which can adapt to the deformation and vibration of the pipeline and reduce the stress concentration of the pipeline, thus prolonging the service life of the pipeline. It has good pressure resistance, corrosion resistance, abrasion resistance, oil resistance and other characteristics, and is widely used in construction, chemical industry, water conservancy, electric power, petroleum and other fields.

This double ball connector with flange allows for secure and flexible pipe connections. Its design allows for efficient and tight fittings, reducing the risk of leakage and ensuring smooth operation. With this connector, you can easily connect pipes of different sizes and materials, increasing versatility and convenience in your plumbing systems.
