The only twist-on for aluminum-to-copper connections. The Twister® AL/CU Wire Connector is the only UL Listed aluminum-to-copper twist-on connector that prevents aluminum oxidation while providing a secure connection. Filled with an anti-oxidant compound, the Twister® AL/CU easily twists on with swept-wings making a comfortable connection with improved conductivity and cooler connections. The live-action spring expands and contracts with aluminum wire to ensure a secure connection while the hexagonal head makes for quick and easy installation by hand or with a standard nut driver.
