Rubber expansion joints are produced by mixing internal and external rubber layers and adopting vulcanization process. Smooth and seamless marks, combined with products, have the characteristics of high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration absorption, good noise reduction effect, and easy installation.

The role of rubber joints: flexible rubber joints can greatly reduce the vibration and noise of the pipeline system, and can fundamentally solve the problems of interface displacement, axial expansion and different centering of various pipelines.

According to different materials, the rubber joints can be made acid-resistant and resistant Alkali, corrosion resistance, oil resistance, heat resistance and other varieties, adapt to a variety of media and environments.

The rubber joint used in the automatic constant pressure water replenishment exhaust device can reduce the vibration and noise caused by the liquid passing, increase the service life of the product, improve the safety factor, and reduce the maintenance cost.
