PPR pipes (Polypropylene Random Copolymer) are high-grade plastic pipes widely used in modern plumbing for hot and cold water systems. Known for their green or white color, they handle extreme temperatures (-20°C to 95°C) and high water pressure without cracking. They are joined via heat fusion, fusing pipes and fittings into one leak-proof piece that can last over 50 years. [1, 2, 3, 4, 5, 6, 7]
