The PVC Round-to-Flat Reducing Coupling is a specialized connector designed for pipe systems, primarily used to facilitate the transition between round pipes and flat pipes. Made from high-quality PVC material, this product offers corrosion resistance and anti-aging properties, making it suitable for various industrial and residential drainage, ventilation, and water supply systems.
The coupling has a specification of D110x100mm, indicating that the diameter of the round port is 110mm, while the flat port measures 100mm. This design effectively reduces the pipe diameter, meeting the requirements for connecting pipes of different sizes. The product's construction is meticulously calculated to ensure sealing and stability during connection, preventing leaks and loosening.
The surface of the PVC Round-to-Flat Reducing Coupling is smooth and free of burrs, allowing for easy installation without additional tools. Connections can be made through simple threading or clamping methods, significantly improving construction efficiency. Its lightweight yet robust structure makes transportation and installation more convenient, reducing labor costs.
