Product Details

Flexible Threaded Rubber Joint

Flexible threaded rubber joint consists of rubber tube and metallic flexible joint. Rubber tube composes of inner glue line, outer glue line and multi-scratch rubber cord enhancement layer. This joint has many advantages such as high patience, good elasticity, large deflection displacement, good shock-absorbing. It is widely used in fan coil units pipelines in the room of hotel and restaurant.
