hose extension connector adapters, hose nuts; brass; 1/4" (6.35mm or 6mm), 3/8" (9.52mm or 10mm); suitable for various air conditioning pipe installation and maintenance scenarios. The AC hose pipe connector is made of brass, with durability, corrosion resistance and performance, and has a service life. The air conditioning hose connection adapter is mainly used to replace an old and faulty refrigerator compressor, as well as to connect and extend the copper pipes of air conditioners, refrigerators, and refrigeration systems. It can also be used in fuel and gas systems, plumbing and vacuum applications. The flare nut, thanks to its special threaded shape and structure, applies uniform pressure to secure the hose connection, prevent leaks, and ensure the air conditioner's sealing. Place the flare nuts at the ends of the two copper pipes, connect the two ends using the connection adapter, then tighten the nuts with a wrench. These copper pipe fittings are designed and their specifications can meet your copper pipe extension needs. Please check the size before purchasing.
