Concentric reducing rubber joints, also known as reducing rubber joints, flexible rubber joints, flexible rubber joints, etc. The tubular elastic element is composed of inner and outer layers of rubber, ply and steel ring, which is formed by high temperature and high pressure vulcanization and then loosely combined with metal flanges or parallel joints. It has the characteristics of acid, alkali and oil resistance. Hot-melt connection can be used during installation, which is convenient for installation; saves energy; applicable media are: water, sewage, seawater, drinking water, hot and cold water and other highly corrosive media, as well as a variety of acid, alkali and salt solutions.

Product features of Concentric reducer rubber joint
1. Concentric reducer rubber joint is made of inner rubber layer, reinforced layer with multi-layer scraper nylon cord fabric and reinforced skeleton material sandwiched with glass fiber reinforced cloth. High temperature mold vulcanization forming.
2. Due to the structural characteristics of the product, it is especially suitable for the connection of pipe bends
3. The spherical surface of the Concentric reducer rubber joint is smooth and wrinkle-free and there is no mortar residue in the sphere, so its quality is better
4. The material of Concentric reducer rubber joint is carbon steel and stainless steel.
5. Centrifugal casting process is a new type of process technology developed in the past ten years. This process uses a die to seal the end of the tube, then inject liquid to cool the tube and shrink it, and then throw out the model with a centrifuge to obtain hollow blank pipe products.
6. The product has high internal density and can withstand high pressure
7. According to user requirements, we can also produce other concentric special-shaped products with different sizes and sizes
8. The concentric reducing three-way expansion joint is mainly used for the connection between the inlet and outlet of the pump
9. Brass is generally used for fire protection
10. Concentric reducer rubber joints are used in water supply to make concentric coaxial seals, bolt glands, nut gaskets, and O-rings, and are used on valves with vertical displacement ≤40mm.
