It quickly joins a 3-inch male camlock to a 2-1/2-inch male fire-hose connection, allowing fast, tool‑free coupling and uncoupling. Commonly used on fire trucks, tanker trucks, and sprayer equipment for water or liquid transfer. Replace when the aluminum body is cracked, the cam arms no longer lock securely, or the Buna seal shows signs of swelling/cracking, which can cause leaks under pressure.
