Copper Connection

Designed for secure and dependable copper line connections, this 5/8 inch (15.88mm) aluminum flare nut is a vital component for standard split-system air conditioners and heat pumps. It evenly distributes tightening torque against the flared copper tube end to prevent refrigerant leaks under high operational pressures. Built to resist vibration fatigue and environmental degradation, it ensures a tight, professional-grade mechanical joint that simplifies both installation and future maintenance tasks.
