Core Features
Material Safety and Hygiene
The main PPR material is lead-free, non-toxic, and corrosion-resistant, complying with drinking water hygiene standards and can be directly used for domestic drinking water transportation; the brass insert adopts an environmentally friendly lead-free formula (meeting NSF/WRAS certification), avoiding metal precipitation to contaminate water quality, suitable for healthy home needs.
Structural Reinforcement and Sealing Performance
The female threaded interface undergoes precision turning processing, with thread accuracy meeting GB/T 7306 standards, fitting closely with metal external threaded accessories; the branch part features a thickened wall design to enhance pressure-bearing capacity and reduce stress concentration caused by water flow impact; PPR and brass inserts are combined through molecular-level bonding technology to eliminate the risk of delamination and leakage.
Temperature and Pressure Resistance with Longevity
The long-term working temperature range is -10℃~70℃, and it can withstand high temperatures of 95℃ for a short time; the pressure rating covers PN16 (1.6MPa) and PN20 (2.0MPa), meeting the pressure requirements of household, commercial and general industrial systems; under normal working conditions, the service life can reach more than 50 years, without the need for frequent replacement and maintenance.
Strong Installation Adaptability
The PPR port supports hot-melt connection, forming an overall sealed structure after being fused with PPR pipes of the same specification; the female threaded interface is compatible with standard metal pipe fittings, enabling flexible docking with valves, water meters, water pumps and other equipment, with a simple and easy-to-operate installation process.
Technical Advantages
Material Composite Technology
Adopting "PPR - brass" heterogeneous material integrated injection molding technology, by optimizing mold temperature and injection pressure, the PPR melt and brass surface form a dual bonding force of mechanical interlocking + chemical adhesion, solving the industry pain point of traditional inserts being prone to loosening and water leakage, with no abnormalities in cold and hot cycle tests.
Hydrodynamic Optimization
The internal flow channel adopts a streamlined design to reduce water flow resistance at the branch, lower the impact of water hammer effect on the pipeline, and at the same time reduce noise and energy consumption.
Full-Scenario Compatibility
Adaptable to various piping systems: cold and hot water supply, floor heating manifold, central air-conditioning water circulation, solar hot water connection, etc.; compatible with different installation environments: exposed installation, concealed installation, wall embedding, no special protection required.
Product Applications
Residential Building Water Supply Systems
Home Kitchen: Main pipeline branches to connect water heaters, dishwashers, water purifiers (female threaded interface docks with equipment valves).
Bathroom: Cold and hot water pipes divert to showers, bathtubs, toilet water tanks, connecting angle valves or thermostatic valves through female threaded interfaces.
Whole-House Water Pipeline Renovation: Branches after water meters, connection points between main pipes and branch pipes, realizing the diversion demand of "one pipe in, multiple pipes out".
HVAC and Comfort Systems
Floor Heating Systems: Connection between manifolds and main pipelines, with female threaded interfaces docking with thermostatic valves or circulation pumps.
Central Air-Conditioning: Water circulation pipeline branches, connecting metal interface components of fan coils or heat exchangers.
With reliable connection performance and wide adaptability, the PPR female threaded tee has become a core fitting in various fluid systems for achieving seamless connection between "PPR pipelines and metal equipment", providing a fundamental guarantee for the safe and stable operation of the system.
