Our air conditioning pipes and split valves are manufactured using high-quality copper and brass, ensuring excellent durability, thermal conductivity, and corrosion resistance.
They are designed to be fully compatible with R22 and R410 refrigerants, making them suitable for standard HVAC and air conditioning systems.
You can refer to the horsepower and model table above to find a match. However, because specifications may vary among different brands, we highly recommend measuring the outer diameter of the copper tube or the nut to confirm before purchasing.
No, the specifications of copper tubes used by different brands and newer 3-horsepower air conditioner models on the market are not uniform. You must measure and confirm the exact size beforehand.
These products are widely used in the construction industry, industrial machinery, and various air conditioning and refrigeration systems.
