b) Technology: We introduce advanced technology from abroad, and combine it with Chinese manufacture experience. In the manufacturing process, the inner side endures high pressure; nylon cord fabrics and the inner rubber are better combined and can work under higher pressure than normal flexible rubber pipe joints.

c) Features: The inner adhesive layer united perfectly, bright, clean and seamless; the tag adopts the vulcanization process, perfectly matches the product. The products endure high pressure, maintain good elasticity, make large displacement to balance pipe deviation, absorb vibration, make less noise and have easy installation, etc.
