The Firestone Union Tee is a 3/8 in push‑lock air fitting that joins two air springs so you can equalize pressure without adjusting each bag individually. It streamlines air suspension plumbing for matched ride and load control. Packaged as a 25‑count set, the nickel push‑lock tees are sized for 3/8 in tubing and simplify installation and routine maintenance of air lines.
