Hybrid Structural Logic: Combines a high-strength brass threaded insert with a durable PPR-80 housing, providing the perfect interface between modern plastic piping and traditional metal fixtures.
Knurled Brass Anchorage: The brass insert features deep external knurling to lock into the PPR body during injection molding, preventing the insert from rotating or loosening during high-torque installation.
Corrosion-Resistant Interior: The brass alloy is specifically selected for its resistance to dezincification and mineral scaling, ensuring long-term flow efficiency in hard-water areas.
Thermal Expansion Resilience: Engineered to absorb the differential expansion rates between metal and polymer, maintaining a leak-proof seal even during rapid temperature shifts in hot water lines.
Precision Internal Threading: Standardized BSP threads ensure a smooth, secure connection with faucets, mixers, and other sanitary equipment without the risk of cross-threading.
