Products Description
Precision Copper Tubing Components
Product Introduction
This series of copper tubing components acts as the critical bridge between the indoor and outdoor units of an HVAC system. Designed for optimal refrigerant flow, these fabricated tube sets eliminate the need for on-site cutting and bending, streamlining your air conditioning manufacturing process.
Engineered Exactly to Your Specifications
We understand that every AC unit requires a unique piping layout. Our factory provides highly flexible manufacturing, allowing you to specify exact flaring hole dimensions and bending radii to perfectly match your assembly line requirements.Why Choose Our Components?
- Premium Brazing Integrity: Fabricated with high-grade copper materials and advanced brazing techniques, ensuring robust joints that remain completely stable across various refrigerant types.
- 100% Nitrogen Leak-Tested: Each component is subjected to rigorous pressure testing to guarantee a zero-leak rate. The internal bores are thoroughly purged, leaving no oxidation scale or flux residue.
- Wide Refrigerant Range: Fully compatible with modern eco-friendly and traditional refrigerants, including R134a, R22, R407C, R410A, and R32.
- High-Pressure Durability: Built to withstand severe operational stress with a maximum working pressure of 4.2 MPa, ensuring safety and longevity in extreme temperatures.

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
