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

    Medium-Pressure Aluminum Butt-Weld Pipe Fittings

    Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow. Fittings are lightweight with good corrosion resistance.
