| Product Description
PPR Fittings (S2.5) are pipe connection products manufactured from high-quality polypropylene random copolymer (PP-R) raw materials through precision injection molding technology. Together with PPR pipes, they form a complete piping system. Using heat fusion connection technology, the pipe and fittings create an integrated structure with no visible boundary. This product series covers all categories from couplings, elbows, tees to unions, valves, and more, widely applied in building hot/cold water systems, pure water delivery, heating, and central air conditioning.
| Product Feature
● Same-Material Fusion for Zero-Leak Systems: Manufactured from the same raw materials as PPR pipes, PPR Fittings (S2.5) form a fully integrated piping system after heat fusion, with joints having no interfaces or weak points, truly achieving 50-year leak-proof performance under normal operating conditions.
● Complete Product Range for One-Stop Procurement: The product line comprehensively covers couplings, 90° elbows, 45° elbows, equal tees, reducing fittings, male/female threaded adapters, unions, stop valves, ball valves, and more, meeting one-stop procurement needs for various projects.
● Precision Injection Molding with Accurate Dimensions: Utilizing high-precision molds and injection processes ensures that each PPR Fitting (S2.5) strictly complies with standards for socket depth and inner diameter dimensions, providing tight pipe matching and reliable fusion quality.
● Pure Raw Materials for Hygienic Safety: PPR Fittings (S2.5) meet various countries hygiene standards for direct drinking water piping systems, being non-toxic and odorless, ensuring water safety.
● Corrosion Resistance for Long-Lasting Durability: PPR Fittings (S2.5) are chemically inert to all ions in water and chemicals in buildings, preventing scaling and corrosion, eliminating the rust blockage and yellow stain issues common with metal fittings.

I Comparison with Other Materials
Comparison Dimension | PPR Fittings (S2.5) | Galvanized Metal Fittings | PVC-U Fittings |
Connection Reliability | Heat fusion, integrates with pipe, no leakage risk | Threaded connection, prone to loosening from vibration, sealing points susceptible to leakage | Adhesive bonding, susceptible to temperature-induced debonding |
Corrosion Resistance | Excellent, rust-proof, corrosion-proof, acid/alkali resistant | Poor, easily rusts, scales, affecting water quality | Good, but not high-temperature resistant |
Temperature Resistance | Long-term 70°C, momentary 95°C | High-temperature resistant, but heat accelerates corrosion | Cold water only (≤45°C) |
Installation Convenience | Lightweight, quick heat fusion connection | Heavy, requires threading, labor-intensive installation | Lightweight, but requires adhesive curing time |
Comprehensive Cost | Medium, long service life, maintenance-free | High material and labor cost, significant maintenance expenses | Low, but application-limited |
Hygienic Performance | Non-toxic, odorless, compliant with drinking water standards | Easily rusts, yellow stains contaminate water quality | Additives may leach |

I FAQ
1. What are the common types of PPR Fittings (S2.5) and how to select them?
● Answer: Common PPR Fittings (S2.5) include: Couplings (for straight pipe extension), Elbows (90° or 45° direction changes), Tees (branch connections), Reducing Fittings (diameter transitions), Male/Female Threaded Adapters (connecting metal water appliances), Unions (detachable connections), Stop Valves/Ball Valves (water flow control), etc. Selection should be based on piping design drawings, according to required specifications, directions, and functional applications.
2. How to distinguish the quality of PPR Fittings (S2.5)?
● Answer: Look for well-known brands and large manufacturers, as they can provide international quality certifications and test reports.
3. Can PPR Fittings (S2.5) be directly connected to metal pipes?
● Answer: Yes, but transition adapters with inserts must be used.
4. What are your company’s delivery times for PPR Fittings (S2.5)?
● Answer: Standard stock products typically ship within 7 working days. Bulk custom orders generally complete production and ship within 15-25 working days depending on quantity. Volume discounts are available.
