Aluminum Tube Fittings, Valves

Aluminum Tube Fittings & Valves | Air Conditioning


Developed to meet the improvement requests from the air conditioning and heating systems manufacturers, our innovative aluminum tube fittings and valves can be installed using the threaded Lok-fitting connection method when no welding is required. Assembled with moderate torque rate, our aluminum  fittings and valves provide clear visual confirmation of the installation. Requiring less installation time than other conventional solder joint copper fittings, our products ensure the labor and equipment costs reductions.

Original Lok ferrules and O-rings provide complete airtight sealing. The anti-slip clip tightly grabs a tube providing stable and proper installation. Our fittings are specially designed so that the ferrule will not be assembled if inserted in a wrong direction. Any worker can fasten the fitting, as no training is required.

Our fittings and valves can be used in conjunction with different types of tubes, including copper, aluminum, and the new products on the market – polyamide coated aluminum and powder coated aluminum.
