It allows branching a single air line into two, commonly found in air brake, suspension, or accessory circuits. Replace it when the fitting is cracked, corroded, or leaks air, which can cause a drop in system pressure. Installation is straightforward: cut the tubing square, slide on the compression nuts, and tighten them onto the tee.
