Set up a compressed air system with the 3/4-Inch Maxline Master Kit with 3 air outlet locations. The Maxline tubing has an aluminum core sandwiched between an inner and outer layer of polyethylene. Tubing can be mounted on wall surfaces, in wall, or buried underground or concrete. Tubing holds any hand bent shape. Reduce shop clutter with this industrial compressed air piping system. No glue, soldering or crimping needed. Simply cut the tubing to length, insert in the fitting and tighten. Easy to expand with more air outlet locations or modify later.
