OEM vs. Generic

The OEM tube is sized to the exact bore, length, and fitting required for correct refrigerant flow and a leak-free brazed connection. Generic substitutes may differ in inner diameter or flare, disrupting metering and risking refrigerant leaks. For accurate flow and a proper seal, choose the OEM inlet tube.

Installation Difficulty

Professional (4/5) — Refrigerant work required. A licensed HVAC technician must recover refrigerant, braze the connection, pull a vacuum, and recharge the system. Not a DIY repair due to EPA refrigerant-handling regulations and brazing requirements.
