| Product Description
PPR Fittings (S2.0 Series) belong to the high-pressure rating category, with the pipe series value S2.0 corresponding to higher wall thickness requirements, achieving PN values up to 3.2MPa (at C=1.25) or 2.5MPa (at C=1.5). These fittings are manufactured from high-quality PP-R raw materials through injection molding, specifically designed for industrial high-pressure transmission, high-rise building water supply, and special operating condition piping systems. Compared to conventional series such as S2.5 and S3.2, S2.0 series fittings feature thicker wall structures capable of withstanding higher working pressures, meeting long-term stable operation requirements under demanding conditions .
| Product Feature
● Thickened Wall Design with Exceptional Pressure Capacity: The wall thickness standard for S2.0 series fittings exceeds conventional models. This thickened structure provides superior deformation resistance and safety redundancy under high-pressure operating conditions.
● Compatible with High-Pressure Systems with Enhanced Safety Factors: When the safety coefficient C=1.25, S2.0 fittings achieve a nominal pressure rating of 3.2MPa; at C=1.5, they still reach 2.5MPa. This means under identical operating conditions, the S2.0 series offers higher safety margins, particularly suitable for locations with stringent system safety requirements.
● Broad Spectrum Applicability for Both Cold and Hot Water: S2.0 series fittings are not only suitable for cold water systems (≤40°C) but also perfectly compatible with hot water systems, meeting long-term operating temperatures of 70°C and momentary temperatures up to 95°C. For critical applications with long-term operating temperatures reaching 70°C or higher, the S2.0 series represents an ideal choice.
● Standardized Interfaces with Strong Versatility: Despite increased wall thickness, the interface dimensions of S2.0 series fittings comply with ISO 15874 standards, maintaining full compatibility with same-specification pipes and conventional fusion tools, ensuring installation convenience remains unaffected.

I FAQ
1. What is the main difference between S2.0 series fittings and S2.5 series?
● Answer: The primary difference lies in wall thickness and pressure capacity. At safety coefficient C=1.25, S2.0 achieves PN value of 3.2MPa, while S2.5 achieves 2.5MPa. S2.0 is suitable for higher pressure requirements, such as pressurized systems in super high-rise buildings and industrial high-pressure pipelines .
2. Can my existing fusion tools be used for S2.0 fittings?
● Answer: Yes, but it's important to pay attention to the mold head compatibility. The outer diameter interface size of the S2.0 pipe fittings is consistent with that of standard pipe fittings of the same specification. Therefore, standard hot-melt mold heads can be used universally. However, due to the increase in wall thickness, the heating time needs to be appropriately extended by 10-15% to ensure complete melting. It is recommended to conduct trial welding verification before the formal construction.
3. What are the delivery time?
● Answer: Stock products typically ship within 5-7 working days; custom orders complete within 15-20 working days depending on quantity. Volume discounts are available.
