Air conditioning copper pipe duoble connector

Air conditioning copper pipe duoble connector are core fittings for connecting two copper pipes in air conditioning systems. Adapters on both ends allow for precise connection of copper pipes of the same or different diameters, ensuring smooth refrigerant transmission and preventing leaks.
They are used for residential and commercial air conditioning pipe extensions, repair splicing, and new unit piping assembly.
Made of brass, precision-turned and seal-tested, they feature refrigerant-resistant sealing rings and are compatible with a variety of refrigerant types.
Our service includes selection guidance. Advantages include stable connections, excellent sealing, corrosion resistance, and a wide range of compatibility.
The air conditioning copper pipe duoble connector is the core connecting pipe fitting for connecting two copper pipes in the air conditioning piping system. Its core advantages are "double-end precise docking + long-term sealing and leak prevention". It is made of high-quality H62/H65 brass through cold heading and then precision turning the double-end interface. The thread accuracy reaches 6H level. The inner wall is equipped with refrigerant-resistant nitrile rubber sealing rings suitable for the corresponding pipe diameter. After tightening, the bell mouths of the double-ended copper pipes can be tightly fitted at the same time. The brass material has excellent corrosion resistance and is suitable for air conditioning operating conditions of -30℃~120℃, avoiding interface deformation or sealing failure caused by temperature changes. It covers over 10 mainstream pipe diameter combinations and is compatible with various refrigerant systems, including R22, R410A, and R32. Some models feature a stepped positioning structure, allowing for quick alignment of copper pipes during installation, reducing the risk of misconnections. The interfaces are equipped with anti-slip hexagonal surfaces, preventing wrench slippage and improving installation efficiency. The sealing ring utilizes an integrated vulcanization process, which tightly adheres to the inner wall of the interface to prevent loss or removal. It is compatible with the pipe thread standards of various domestic and international air conditioner brands. Applications include extending residential air conditioning pipes, splicing branch pipes for commercial central air conditioners, emergency splicing of copper pipe breaks during air conditioner maintenance, and pipe assembly during new unit installations. It not only addresses copper pipe connection needs in various scenarios, but also ensures the refrigerant sealing and smooth transmission of the piping system, reducing cooling efficiency reduction or refrigerant leakage caused by improper connections.
