1. Small size, light weight, good flexibility, easy installation and maintenance.
2. After installation, it can absorb the horizontal, axial and angular displacement caused by the vibration of the pipeline; it is not restricted by the non-concentricity of the pipeline and the non-parallel flange.
3. After installation, it can reduce the noise generated by the vibration of pipes, pumps, etc., and has a strong vibration absorption capacity.
4. The internal seamless high-pressure rubber joint can more effectively prevent the corrosive medium from corroding the inner wall of the rubber joint in high temperature, acid and alkali resistant, and oil resistant pipelines, and improve the service life.

ZG rubber joints have good comprehensive performance and are widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, and electric power. According to different materials, it can be made into various varieties such as acid resistance, alkali resistance, corrosion resistance, oil resistance, high temperature resistance, radiation resistance, abrasion resistance, and aging resistance, which can be adapted to various media and environments.
Note:The joints above DN200 used in high pressure and high building,anti-pull-off device should be installed if the pipe has no fixed stay or fixed bracket(actual axial force of the product is less than anti-supporting force).
