Our simple, 6' water hose extension lines for your TIG welder with water-cooler setup are available in two versions (the option you choose depends on your needs). The male to female extension features a 5/8"-18 LH male fitting to connect to your cooler and a 5/8"-18 LH female fitting to thread onto the water line on your TIG welding torch. The male to male extension features 5/8"-18 LH fittings on both ends. Use the male to male extension to connect your power adapter (i.e., 45V11) to your water-cooler.
Hose can be either black as shown or red depending on stock
