Explore our core selection of industrial-grade taps and bibcocks designed for high durability and strict flow control.
Ehao Plastic Group is a high-tech private enterprise integrating R&D and production of building materials, pipe fittings, and high-precision injection moulds. Ehao Plastic Group is a recognized leader in PVC/UPVC ball valves, bibcocks, and taps in the domestic Chinese market, with an ever-expanding global footprint.
Since its inception, our engineering progress has been supported by the technological prowess of the Chinese Academy of Sciences and Zhejiang University. By bridging academic polymer research with commercial manufacturing demands, we have developed advanced material configurations that optimize tensile strength, chemical resistance, and long-term durability.
To maintain absolute production precision, we imported advanced production lines and computerized automatic injection molding machinery directly from Germany. Every valve, bibcock, and tap undergoes a strict 26-step scientific testing process to ensure a 100% ex-factory pass rate. Our products fully comply with DIN8077 and DIN8078 international standards, confirming world-class quality.

Strategic insights for procurement directors, distribution channels, and engineering contractors.
In modern water management systems, global procurement teams are shifting away from traditional brass and bronze bibcocks toward high-grade thermoplastic alternatives (UPVC, PP, PC). This transition is driven by three main factors:
International infrastructure projects require components that meet recognized standards. Ehao Plastic Group ensures compliance through our research partnerships with Zhejiang University and the Chinese Academy of Sciences. Our manufacturing processes conform to:
| Standard Ref | Application Field | Key Testing Metrics |
|---|---|---|
| DIN 8077 / 8078 | Polypropylene (PP) Pipes & Fittings | Hydrostatic pressure resistance, thermal stability, dimensional tolerances. |
| ISO 9001:2015 | General Quality Management Systems | Full traceability, raw material verification, continuous improvement audits. |
| NSF / ANSI 61 Compliant | Drinking Water System Components | Toxicological evaluation, material safety, zero harmful chemical migration. |
