Products Description
Pre-Fabricated HVAC Copper Piping
Optimized for Assembly & Repair
Designed to bridge the indoor and outdoor units of HVAC systems, our pre-fabricated copper piping ensures reliable refrigerant transfer. By delivering these tubes fully processed—flared and bent to exact geometries—we help both OEM assembly lines and aftermarket repair centers eliminate on-site fabrication time.
Agile OEM Customization
Whether you are rolling out a new AC model or sourcing replacement parts for existing units, our flexible manufacturing setup allows us to tailor tube diameters, flaring sizes, and bending radii strictly to your provided blueprints. Rapid prototyping and flexible batch sizes are available.Product Highlights
- Strict Brazing Standards: All connections are expertly brazed with high-grade copper materials, forming durable joints that resist vibration and thermal stress over extended periods.
- 100% Air-Tightness Testing: Every piping assembly is pressure-tested and inspected. The internal surfaces are free of flux and oxidation, ensuring zero leaks and preventing system blockages.
- Broad Refrigerant Adaptability: Built to excel across a variety of systems, seamlessly handling R134a, R22, R407C, R410A, R32, and other common refrigerants.
- Rugged Pressure Performance: Designed for high-pressure HVAC applications, with a maximum working pressure limit of 4.2 MPa and stable operation in -30°C to +120°C environments.

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
