Description
The Mueller Industries W03021 Elbow is a copper tubing fitting used to change the direction of refrigerant or fluid flow within piping networks. It features a 1/2-inch outside diameter connection and a 45-degree angled bend, allowing smooth redirection of line sets with reduced flow resistance compared to sharp turns. Installed in air conditioning, heat pump, and refrigeration line assemblies, it is joined through brazed or soldered connections to ensure a sealed pathway. In HVAC systems, it is commonly applied in refrigerant circuits where directional changes are required within compact installation spaces.
