Bulk HVAC Copper Pipe Sets
Scalable Solutions for AC Manufacturers
Optimize your procurement and production costs with our factory-direct copper pipe sets. Functioning as the critical flow channels between the indoor and outdoor AC units, these pre-fabricated assemblies are built for mass production environments, ensuring every unit fits perfectly into your assembly sequence.
High-Volume Custom Fabrication
We are equipped to handle large-scale OEM orders. Whether your production line requires specific flaring dimensions, unique bend angles, or distinct tube lengths, we provide rapid tooling and consistent mass production to meet your strict deadlines.Manufacturing Advantages
- Direct-from-Source Quality: By cutting out the middleman, we deliver premium quality brazed joints at highly competitive bulk prices, boosting your product's profit margin.
- Strict Source Control: Every batch of copper tubing is rigorously inspected. Post-brazing, each assembly is subjected to an air-tightness test under pressure, guaranteeing 100% leak-free and debris-free delivery.
- Global Refrigerant Standards: Fully engineered to handle high-pressure operations with R410A and R32, as well as traditional gases like R134a, R22, and R407C.
- Heavy-Duty Construction: Our pipes are rated for a maximum working pressure of 4.2 MPa, ensuring they hold up perfectly in extreme temperatures ranging 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
