PPR (Polypropylene Random Copolymer) water supply pipe fitting molds have several advantages over other types of molds for water supply systems. Some of the advantages are:

1. Corrosion Resistance: PPR water supply pipe fittings are made of high-quality polypropylene material, which makes them highly resistant to corrosion and chemicals. This ensures that the fittings have a long service life and maintain their structural integrity over time.

2. High Temperature Resistance: PPR pipe fittings have excellent high-temperature resistance and can withstand hot water at temperatures up to 90°C, making them suitable for use in hot water supply systems.

3. Good Sealing Performance: PPR pipe fittings have good sealing performance, which means they effectively prevent water leakage and maintain water pressure, improving the overall efficiency of the water supply system.

4. Easy to Install: PPR pipe fittings are easy to install, with a simple and efficient installation process that requires no welding or special tools. This reduces installation time and labor costs.

5. Hygienic and Safe: PPR pipe fittings are non-toxic, odorless, and hygienic, making them a safe option for drinking water supply systems.

Overall, PPR water supply pipe fitting molds offer numerous advantages, including corrosion resistance, high-temperature resistance, good sealing performance, ease of installation, and safety and hygiene. These advantages make them a popular choice for water supply systems in residential, commercial, and industrial settings.
