1. Small size, light weight, good elasticity, easy installation and maintenance.

2. It can produce lateral, axial and angular displacement during installation, and it is not restricted by the user's pipeline is not thorough, the flange is not parallel.

3. It can reduce the structure transmission noise while working, and has strong vibration absorption ability.

4. The self-developed internal seamless high-pressure rubber joint effectively prevents the corrosive medium from corroding the inner wall of the rubber joint in pipelines resistant to high temperature, acid, alkali and oil, and improves the service life.

Scope of use :

Due to the good comprehensive performance of flexible rubber joints, it is widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light, heavy industry, freezing, sanitary and plumbing, fire protection, electricity, etc.
