Along with the high quality welding comes a lifetime leak free design. Simply attach your accessory to the welded fitting on the tank using a tri-clamp gasket and clamp; that’s it. Ditch weld-less fittings that are clumsy to install and have o-rings which will leak and fail at some point. Weld-less designs are a cheaper, inferior connection that you will not find anywhere on the professional scale. Additionally the tri-clamp fittings feature no threads. Tri-clamps are the easiest connection to clean and are the industry standard connection for commercial food and beverage operations.
