Engineered for high mechanical strength, chemical resistance, and long service life. Explore our core range of piping connections.
Ehao Plastic Group is a high-tech private enterprise integrating R&D and production of building materials, industrial pipe fittings, and high-precision injection moulds. Notably, Ehao Plastic Group has established itself as an undisputed leader in the PVC/UPVC ball valves and compression fittings sector in the domestic Chinese market, leveraging robust institutional technology and state-of-the-art automation.
Since its inception, our research methodologies and development pipelines have been actively supported by the Chinese Academy of Sciences and Zhejiang University. These collaborative academia-industry links ensure that Ehao remains at the absolute cutting edge of polymer material science and fluid control systems design.
To support global supply chains and high-tolerance municipal demands, we have introduced complete production lines and computer-controlled automatic injection molding systems directly from Germany. This ensures our dimensional accuracy meets the most rigorous international guidelines.
By blending academic research with German engineering precision, our technical indexes reach the world-class tier. Ehao products confidently perform in extreme temperatures, high hydrostatic environments, and complex corrosive chemical applications.
Discover how Ehao Plastic Group delivers unprecedented structural reliability through mechanical validation and structural polymer integrity.
Our plastic compression fittings and valves utilize custom-blended PP-R, UPVC, and HDPE resins optimized with heat stabilizers and UV inhibitors. This delivers outstanding tensile strength and long-term resistance to environmental stress cracking.
Every production run is subjected to 26 individual scientific tests, including hydrostatic pressure testing, dimensional validation under thermal expansion, long-term stress rupture testing, and leak inspection. We enforce a zero-leak policy.
Our integration of German automated injection molding systems guarantees uniform wall thickness and minimizes micro-voiding during the polymer cure cycle. This consistency prevents sudden structural failures under high surge pressure.
Understanding the technical paradigms shaping the global market for municipal and agricultural fluid dynamics.
Global agriculture is transitioning towards high-efficiency precision drip systems. Pipeline infrastructure is expected to operate at higher localized pressures with zero allowance for joint slippage. Our plastic compression fittings address this by employing high-grip clinching rings (collets) and specialized EPDM O-rings, providing a radial seal that tightens as longitudinal load increases. This mechanical grip eliminates the need for solvent welding in agricultural zones, preventing soil pollution and simplifying onsite installation.
International compliance standards are tightening across Europe and the Americas. Sourcing departments prioritize manufacturers that strictly control monomer residues and heavy metal additives. Ehao Plastic Group products align directly with DIN8077/DIN8078, ensuring our PP water drinking taps and UPVC fittings release no microplastics or heavy metal ions into clean water supplies.
Industrial procurement relies on customizable modular layouts. Beyond pre-fabricated fittings, Ehao manufactures plastic moulds, supplying customized materials, physical samples, and technical CAD diagrams according to client requirements. Our high-tech tool-room can generate customized injection and extrusion molds for custom angles, reduction unions, and hybrid connections to interface seamlessly with legacy pipe systems.
With distribution networks across 28 countries, we maintain strict logistical transparency and certification portfolios. We support international engineering contractors with testing documents, pressure-temperature charts, material safety datasheets (MSDS), and compliance certifications for DIN, ASTM, and ISO standards.
Ehao pipeline systems are designed for optimal performance across multiple specialized sectors.

Answers to key engineering, installation, and procurement questions regarding our plastic compression fitting systems.
Ehao fittings are manufactured utilizing German-engineered computer automatic injection molding machines under the strict supervision of Zhejiang University technology partners. They undergo a 26-step testing protocol to ensure high wall thickness, consistent tolerances, and absolute compliance with DIN8077 and DIN8078 standards.
Yes. Ehao is a high-tech private enterprise that integrates mold R&D. We manufacture custom plastic molds, and can develop and make new products according to customers' specific drawings, samples, or dimensional parameters.
Our UPVC and PP-R products are engineered to support PN10 and PN16 pressure ratings (equivalent to 1.0 MPa and 1.6 MPa, respectively). This makes them ideal for residential water lines, heavy-duty agricultural irrigation, and industrial applications.
Ehao's products are widely used in most Chinese provinces and exported to 28 countries and regions, including core markets in Europe, North & South America, and Southeast Asia. All exports carry full certifications conforming to regional plumbing and chemical standards.
DIN 8077 and DIN 8078 define the strict dimensional tolerances and long-term hydrostatic strength expectations for polypropylene pipes and fittings. Conformance to these German standards guarantees that Ehao fittings will withstand decades of thermal and pressure cycles without catastrophic failure.
