PPSU Fittings
Easy Expansion Installation PPSU Fittings are a combination of fittings made from polyphenylsulfone (PPSU) material designed specifically for use with PEX (cross-linked polyethylene) piping systems. PEX piping is known for its flexibility, ease of installation, and resistance to corrosion. PPSU Fittings leverage the benefits of both materials.
These fittings are used extensively in plumbing applications, especially for potable water systems and radiant heating systems. They provide a reliable connection between PEX pipes, ensuring leak-free performance and long-term durability. PPSU PEX fittings come in various configurations, including couplings, elbows, tees, adapters, and valves, to accommodate different plumbing layouts and requirements.
The use of PPSU material in these fittings enhances their heat resistance, chemical resistance, and overall strength, making them suitable for demanding plumbing environments. Additionally, PPSU fittings are often color-coded for easy identification and installation, helping streamline the plumbing process.
PPSU Fittings Advantages
1. High toughness (suitable for low-temperature condition)
2. High strength, high stiffness
3. Heat resistant and not deformed, heat-resistant temperature up to 207℃
4. High chemical stability and easy cleaning
5. Health and safety, used for the nursing bottles
