1. Specifications: We offer five specifications of toilet fittings to meet the diverse needs of customers. These include an 18cm (7.09in) standard flush pipe, an 18cm (7.09in) standard drain pipe, a standard drain elbow, a D90 drain elbow, and a D90to110 drain elbow. 2. Reliable Materials: The 18cm (7.09in) standard flush pipe, 18cm (7.09in) standard drain pipe, and D90 drain elbow are made of HDPE, while the standard drain elbow and D90to110 drain elbow are made of PVC. HDPE is lightweight and flexible, making it suitable for environments requiring impact resistance. PVC is known for its rigidity and stability, making it ideal for longterm use. 3. Enhanced Flushing Efficiency: Through scientific water flow design, this toilet fitting significantly improves flushing efficiency. Water flows more evenly in straight and curved pipes, reducing unnecessary turbulence and resistance, thereby achieving efficient flushing and helping to conserve water. 4. AntiFouling AntiClogging: The interior of the fitting is smoothed to prevent dirt buildup and reduce the risk of clogging. Both HDPE and PVC materials have antifouling properties, which remain effective even after prolonged use, reducing the frequency of cleaning and maintenance while saving users time and effort.
