Product Description
UPVC Drainage Fittings are precision-manufactured from high-quality unplasticized polyvinyl chloride (UPVC) resin through advanced injection molding technology, ensuring exceptional structural integrity, corrosion resistance, and dimensional accuracy. The material’s inherent properties, combined with precise manufacturing, make the fittings lightweight yet robust, capable of withstanding water pressure, external impacts, and harsh environmental conditions. Each fitting features a smooth inner surface that minimizes fluid resistance, prevents scaling and blockage, and ensures efficient water flow. The fittings adopt bonded or mechanical connection methods, providing excellent sealing performance to eliminate leakage risks. Designed to perfectly match POLYGON’s UPVC drainage pipes, they ensure seamless compatibility and easy assembly, reducing installation time and labor costs. Rigorously tested in CNAS laboratories, the fittings exhibit superior resistance to acids, alkalis, and various corrosive substances, making them suitable for handling domestic wastewater, rainwater, and mild industrial fluids. Additionally, the durable UPVC construction ensures a long service life, maintaining stable performance even in long-term use, and contributing to the overall reliability and efficiency of the drainage system.
