The Black HDPE Female Coupler 20-110mm for Drinking Water is a precision-engineered threaded fitting designed to create secure connections in potable water distribution systems. Manufactured from PE100 grade HDPE with integral female threads, this coupler meets the latest EN 12201-1:2024 and NSF/ANSI 61 standards for drinking water contact, ensuring complete safety and reliability. Available in sizes from 20mm to 110mm OD with BSP and NPT thread options, it provides a versatile solution for connecting HDPE pipes to threaded components like valves, meters, and fixtures. The black coloration includes 2.5% carbon black additive for superior UV resistance, while the one-piece molded construction eliminates potential leak paths. Rated for 16 bar (232 psi) working pressure at 20°C, it offers a service life exceeding 50 years in both buried and above-ground installations, outperforming metal threaded couplings prone to corrosion .
The coupler features precision-machined female threads with a 1.5mm thread pitch that creates a secure seal with compatible male threaded components. The thread root is reinforced with 20% thicker walls to prevent stripping under torque application (35-40 Nm for M16 threads). An integrated EPDM O-ring groove at the thread base provides secondary sealing, eliminating leakage even under pressure fluctuations common in water distribution systems .
The PE100 HDPE material is certified to NSF/ANSI 61 for drinking water system components, ensuring no leaching of harmful substances into potable water. It also meets NSF/ANSI 372 requirements for lead-free content, complying with California, Vermont, Maryland, and Louisiana state laws, as well as the U.S. Safe Drinking Water Act. The material undergoes rigorous testing for extractables, guaranteeing water purity even after long-term exposure .
Formulated with carbon black for UV stability, the coupler resists photo-oxidation in above-ground installations, maintaining flexibility and strength in direct sunlight. It retains 90% of its strength at 40°C, making it suitable for tempered water applications in domestic hot water systems. The HDPE construction provides complete resistance to corrosion from chlorinated water and common disinfectants, ensuring long-term performance in municipal water systems .
This threaded female coupler solves connection challenges in drinking water systems:
• Residential Plumbing: Connects HDPE supply lines to threaded fixtures, valves, and water meters in homes and apartments.
• Commercial Buildings: Links HDPE distribution pipes to threaded components in hotels, hospitals, and office complexes.
• Municipal Service Lines: Transitions between HDPE water mains and threaded service connections to residential and commercial properties.
• Water Treatment: Connects HDPE process lines to threaded monitoring equipment and control valves in treatment facilities .
The black color comes from 2.5% carbon black additive that provides superior UV resistance, protecting against sunlight degradation in above-ground installations while maintaining the material’s structural integrity.
The coupler is available with BSP (British Standard Pipe) and NPT (National Pipe Thread) options, ensuring compatibility with global plumbing components and fixtures.
Yes. It maintains pressure integrity at temperatures up to 40°C with full 16 bar rating, making it suitable for domestic hot water systems and tempered water applications.
The HDPE end is fused to the pipe using socket fusion (260±10°C) or electrofusion, while the threaded end connects to male components with proper torque application and thread sealant compatible with drinking water systems.
