    Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

    Low-Pressure Aluminum Threaded Pipe Fittings

    In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications. To prevent cracking, do not tighten more than a 1/4-turn past hand tight.

    Aluminum One-Way-Flow Rotary Joints

    Image of Product. Front orientation. Contains Annotated. Rotary Joints. Aluminum One-Way-Flow Rotary Joints.
    These joints have a rotating shaft with threads on one end that connect to a continuously revolving drum, roller, or other rotating equipment. Use them to transfer hot and cold materials from your supply line. Joints are for one-way flow and are meant to be used in pairs—one joint serves as the supply line while the other serves as the return line. They are a compact size for use in small air and hydraulic applications.
    Right-Hand Thread—If your drum rotates counterclockwise as you face the connecting end, you should select a rotating joint with right-handed threads.
    Aluminum—Joints are made of lightweight aluminum.
