Weil McLain 560-742-905 Aluminum Tube

The Weil McLain 560-742-905 Aluminum Tube is a 60 inch length of AL3003 aluminum tubing with a 1/4 inch OD and a 0.032 inch wall. It is catalogued as Tube AL3003-0.25OD x 0.032 x 60 in. It is sold as a replacement length of tubing for Weil McLain boilers, and the 60 inch length gives you room to route a new run and trim it to fit.

AL3003 is a commercial aluminum alloy that is easy to bend and cut, which is why it is used for small-diameter tubing runs. The 0.032 inch wall on a 1/4 inch OD tube keeps the material light and workable while still holding its shape once it has been formed. Because the tube is a plain length, the finished run depends on how it is routed and terminated, so follow the boiler manual for the fittings and installation method used on your model. Handle the tubing carefully, avoid kinking it while you bend it, and make sure the cut ends are clean and square before you make a connection.

Weil McLain also sells the same tubing as a shorter 20 inch length under 560-742-880. If a replacement only needs a short run, the shorter length is the closer match, and if you need more reach or want spare material for routing, the 560-742-905 is the 60 inch option. Match the 1/4 inch OD and the 0.032 inch wall to the tube you are replacing, and check the boiler model before ordering, since the part number alone does not tell you which boiler it was installed on.
