| A reducing coupling is a fitting used to connect two pipes of different diameters, ensuring stable operation, leak-tight performance, and long-term durability of piping systems. The product is manufactured from high-quality engineering plastics, suitable for clean water supply, irrigation, drainage, and industrial applications. Construction: – Coupling body: Made from premium PE or PP plastic, offering high pressure resistance and excellent corrosion resistance – Compression nut / locking ring: Applies pressure to securely grip the pipe and ensure tight sealing – Sealing gasket: Made from NBR / EPDM rubber, providing absolute leak-tightness – Retaining ring: Holds the body and gasket firmly in place, enhancing durability under pressure Technical specifications: – Sizes: From Ø25 × Ø20 mm to Ø110 × Ø90 mm – Working pressure: PN10 – PN16 – Material: Virgin PE / PP – Applications: HDPE / LDPE / LLDPE pipes – Standards: ISO 17885, ISO 3458, ISO 3459, ISO 3501, ISO 3503, ISO 7 Key Characteristics: – Smooth diameter reduction design ensures stable flow – High pressure resistance and excellent sealing performance with EPDM gasket – Resistant to corrosion, chemicals, and harsh environments – Easy installation without specialized tools – High durability and long service life Functions: – Connects two pipes of different sizes – Supports diameter transitions in water supply systems – Creates strong, fully watertight joints – Reduces vibration and pipe misalignment at inlet/outlet connection points Benefits: – Easy installation and maintenance – Cost-effective – Excellent compatibility with HDPE pipes – Durable with leak-proof performance – Lightweight and easy to transport – Suitable for PE pipes SDR9–SDR17, black color Disadvantages: – Not suitable for high-temperature environments (>60°C) – Lower mechanical strength compared to metal fittings |
