Copper Pipe Extension Joint Connector Pipe Coupling Adapter with Flare Nut Flare Fitting for Air Conditioning Refrigeration Tube

Specifications:【One-Piece Forged】 Made entirely from thick, precision-forged brass with an anti-oxidation surface treatment, resistant to rust and corrosion. Designed for high-pressure air conditioning refrigerant lines, it offers excellent pressure resistance, ensuring no cracking or refrigerant leakage even under prolonged cycles of heating and cooling—ideal for long-lasting, reliable AC repairs. 【Flare Structure】 Features standard conical flare ends that perfectly match the flaring process used in AC copper tubing. When tightened, they fit snugly with no gaps. Combined with a lock nut for double locking, this design prevents refrigerant leaks completely, eliminates the need for welding, and allows maintenance without open flame operations. 【No-Weld Connection】 No welding required and no need for open-flame tools. Simply flare the copper tube and screw on directly to extend the piping. Safer for home installations and high-altitude AC repairs, eliminating fire hazards associated with welding. Enables single-person, quick and efficient pipe connections. 【Universal Size】 Compatible with standard household AC copper connecting tubes, ideal for extending pipes, repairing damaged sections, or splicing during unit relocation. Suitable for wall-mounted units, floor-standing units, and central air conditioning systems. Highly practical for repair shops and home users alike. 【Hex Nut】 Thickened hexagonal nuts on both ends provide secure grip for wrenches, preventing slippage. Even force distribution ensures tight sealing without stripping threads or damaging teeth. Maintains stable, leak-free performance even after repeated disassembly and reassembly.
