Product Q&A
Q:Are you a trading company or a manufacturer?
A:
We are a leading source manufacturer with 25 years of expertise. Our 15,000 square meter facility in Ningbo is equipped with 200+ precision CNC machines and 65+ automated assembly lines, delivering an annual capacity of over 50 million units.
Q:How do I order the product?
A:
The process involves: Make an inquiry -> customize drawings and samples -> use scenario notification -> receive product design proposals -> negotiate details -> confirm samples -> sign contract and pay deposit -> mass production -> get goods ready -> deliver -> further cooperation.
Q:How do you guarantee the fittings won't leak under high pressure?
A:
We enforce a strict 'Zero-Leakage' standard. Every fitting undergoes 100% pressure-drop leak testing and CCD vision inspection before shipping. We maintain an extreme +/-0.5mm machining tolerance and use premium seals (e.g., NBR) to ensure industrial-grade reliability.
Q:How can I identify the correct thread types during installation?
A:
We utilize Laser-Etched Coding. The exact specification (e.g., 1/4 NPT) is permanently laser-marked on the fitting body, ensuring quick identification and preventing equipment damage from mismatched threads.
Q:Do you offer fittings for special environments like food processing or cleanrooms?
A:
Yes. In addition to standard brass and PBT fittings, we specialize in high-precision 316L Stainless Steel fittings (FDA compliant for food & medical), PFA cleanroom connectors for semiconductors, and chemical-resistant valves.
