Aluminum Couplings are made using a 6061-T6 typical alloy. This product hasleft and rightinternal threads allowinginstallation to be accoplished by rotatingin asingle direction while pulling each duct toward the center of the coupling. There are many sizes available as well as transition couplings from one duct size to another.
