Precision HVAC Copper Tube Sets
High-Fidelity System Integration
Seamlessly connect your HVAC modules with our precision-engineered copper tube sets. These assemblies are not merely pipes; they are crafted to ensure optimal fluid dynamics and structural integrity, meeting the stringent demands of modern air conditioning manufacturing.
Engineered for Your Unique Architecture
Every HVAC chassis has a unique internal architecture. We provide comprehensive customization for pipe diameter, flare geometry, and bend angles based on your CAD files, guaranteeing a precise fit that accelerates your assembly line workflow.Key Engineering Advantages
- Lead-Free Eco-Brazing: We utilize environmentally conscious, lead-free brazing materials that ensure robust joints while complying with global green manufacturing standards.
- Rigorous Quality Assurance: Every piece undergoes 100% nitrogen pressure testing. The inner surfaces are meticulously treated to be completely free of oxidation and flux, safeguarding your compressors.
- Next-Gen Refrigerant Ready: Fully compatible with the latest eco-friendly refrigerants like R32 and R410A, as well as traditional gases such as R134a, R22, and R407C.
- Extreme Pressure Resilience: Manufactured to endure demanding operational environments, with a maximum working pressure of 4.2 MPa and reliable performance from -30°C to +120°C.

Q:1.Do you provide CE/UL certificates for the entire kit?
A: We provide UL/CE certified modules (like filter driers and charge valves) sourced directly from top-tier manufacturers. The certificates and test reports for these specific components come with the shipment. For non-electrical parts (like copper pipes and brackets), we provide material reports and d
Q:2.Are electrical cables included in the kit for the local market?
A: No. To ensure strict compliance and avoid regional electrical certification conflicts (such as CE/UL cable standards), electrical cables are intentionally excluded from our standard mechanical kits. This allows you to source local, fully certified cables and integrate them on your line, keeping your
Q:3.What exactly is included in your standard "Line Set Kit"?
A: Our standard kit includes five core mechanical modules: Y-Joints (or tees), pre-cut copper pipes with insulation, filter driers, charge valves, and vibration eliminators. Optional modules like sight glasses or accumulators are available upon request. We pack them according to your specific machine B
Q:4.Can you customize the copper pipe lengths and kit composition?
A: Yes. Because we aggregate from a flexible, top-tier supply chain, we can customize the copper pipe lengths (pre-cut and flared), insulation thickness, and the specific combination of components based on your exact assembly drawings. You don't need to meet a massive MOQ for the whole kit; we scal
Q:5.How do you handle the shipping and customs clearance documents?
A: Since a kit involves multiple HS codes (copper fittings, valves, brackets), we coordinate the commercial invoice and packing list clearly by item. We work closely with your freight forwarder to ensure the customs declaration matches the physical goods exactly, minimizing the risk of port delays. All
Q:6.What is the typical lead time for a BOM-matched kit?
A: After BOM confirmation and sample approval, the production of the core modules typically takes 20–30 days. Because we consolidate modules at our facility before shipping, you save the time you would normally waste waiting for different factories to deliver to your forwarder. We provide a single, un
