The Firestone Union Tee is a single 1/4 in push‑lock fitting that joins two air lines so you can equalize pressure between air springs without adjusting each bag individually. Supplied as a single unit, the nickel push‑lock tee provides a compact, serviceable junction for suspension plumbing or pneumatic systems and helps maintain matched pressures for consistent ride and load handling.
