What This Listing Includes: One genuine OEM W11504449 refrigeration lokring aluminum reducer coupling - 4 mm to 2 mm as supplied for the manufacturer service application; other adjacent assemblies/hardware are not implied unless specifically stated.
Model Evidence Note: Verified representative models. Model examples are not exhaustive. Always match the complete model number, including suffix/revision where present, against manufacturer service information.
Correct Part / Compatibility Check: Match the complete model number, exact connection location and hose/tube diameter/material. Visual similarity alone is not sufficient.
Distinguish From Similar Parts: Lokring fittings that look similar can have different tube diameters, materials and connection locations. Do not substitute 5/1.8, 5/4, 6/4, 7/5 or other coupler sizes.
Possible Related Symptoms / Reasons to Inspect: Physical damage, wear or a model-specific malfunction traced to this component. Symptoms guide inspection but do not prove part failure.
Important Safety / Service Note: Sealed-system refrigeration work can require refrigerant recovery, leak testing, specialized tools and qualified service. Follow manufacturer procedures and applicable refrigerant-handling requirements.
Ordering Note: Symptoms can identify a system to inspect, but they do not prove this specific component is defective. Confirm the OEM part number or model-specific parts diagram before ordering.
