It ships empty (refrigerant not included) and is purpose‑built with a reverse (left‑hand) 1\/4\" FL‑M connection to prevent accidental cross‑connection to non‑A2L systems. Constructed from heavy‑gauge, powder‑coated steel with an integrated safety collar and relief valve, the unit meets DOT‑4BA400 and Transport Canada standards and arrives clean and ready for immediate use.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the left‑hand threaded connection improve on‑job safety?\u003c\/h3\u003e\n\u003cp\u003eThe cylinder uses a reverse (left‑hand) 1\/4\" FL‑M fitting so A2L hoses and equipment can be clearly distinguished from conventional refrigerant fittings, lowering the chance of cross‑connection.
